Gospel Unity
John 17. My grandfather died when I was 25 years old. He was a man who deeply loved the Lord. At the time of his death I was an unbeliever, living for myself, living in sin, but I remember the last conversation I had with my grandpa, and I specifically remember the last prayer I ever heard him pray. He was dying of cancer, his body was wracked with pain, but in the midst of his own pain he wanted to pray for me. His prayer was short, he was out of breath, but it went like this, “Oh Lord, please save my grandson, please set him free from the devil’s kingdom and please make him useful in yours.” And I’m ashamed to say that in my mind I mocked at that prayer, and mocked at that dying man. But in due time God did save me and set me free, He answered my grandpa’s last prayer.
And today we come to Jesus’ last prayer for His disciples, and in the midst of His own pain as He faces death by crucifixion He ministers to His disciples by praying for them. And look at what Jesus’ last prayer was all about: at the end of vs. 11: “…that they may be One, as we are One.” Look at vs. 21, 21 that all of them may be one, Father, just as you are in me and I am in you.” End of vs. 22: “22 …that they may be one as we are one.” Vs. 23: “23 I in them and you in me. May they be brought to complete unity…” So it’s pretty clear that the heart of Jesus Christ is that His people be unified. And we remember reading that God heard and answered Jesus’ prayer, as Acts 4:32 says, “32 All the believers were one in heart and mind. No one claimed that any of his possessions was his own, but they shared everything they had.” One in heart, one in mind, one in possessions, you just can’t get more unified than that.
But let’s take a second and remind ourselves of what we’ve studied in this chapter. This is our last week in John 17 and it’s important that we remember the context and the content of Jesus’ prayer. So we noticed, first of all, that Jesus prayed about their eternal life. In vs. 3 He says “3 Now this is eternal life: that they may know you, the only true God, and Jesus Christ, whom you have sent.” And we remember that this Word “know” is the word “Ginosko” and it means to become one with. It is a term of intimate union, which is exactly what vs. 23 is referring to when Jesus says, “I in them, and you in me”. So that our knowing God is described in terms of the most intimate of relationships. And as we know God intimately, that is, we become one with Him spiritually, we have eternal life because we have God’s life.
And then we saw in this chapter that during Jesus’ prayer He commends His disciples for two things: in vs. 6 He says “they have obeyed Your Word” and in vs. 10 He says “they have brought Me glory.” And we took just a second to acknowledge that the disciples He was talking about failed often, they stumbled much, their faith was weak, they just plain got it wrong much of the time. And about those people Jesus said, “they have obeyed your word, they brought Me glory”.
You might know that Hebrews chapter 11 is the hall of faith; it lists a lot of people of faith, most of whom got wrong much of their lives: Moses in his anger threw down the 10 commandments and broke them, later in his anger he disobeyed God by hitting a rock instead of speaking to it, and his anger kept him out of the Promised Land. Rahab had lived as a prostitute, Samson had lust and impurity most of his life, David had been an adulterer and murderer, and on and on it goes, but at the end of Hebrews 11, vs. 39 summarizes their lives and says: “39 These were all commended for their faith…”, and we learn that even weak faith is commendable faith, and we who stumble often and get it wrong are encouraged. Jesus says about His weak, faltering, fearful disciples, and about you and me today: “They obeyed Your Word, they brought Me glory.”
And then we’ve seen in John 17 that Jesus prays for two things for His disciples: in vs. 11 He prays for their protection. He was about to leave and go to His Father and according to vs. 14 He was leaving them in a world that hated them, in vs. 15 a world ruled by the evil one who is described as a roaring lion, and a devouring dragon. If you can picture roaring lions and fire-breathing dragons chasing after helpless men and women you’ll have a picture of what we are up against today, and you’ll know why Jesus prayed for His disciples.
And then we remembered the reason why the world hated them, as vs. 14 says “I have given them Your Word, and the world has hated them.” Isn’t it amazing that the very source of our joy is the source of the world’s hatred of us? We see that by comparing vss. 13 and 14. Vs. 13 13 “I am coming to you now, but I say these things while I am still in the world, so that they may have the full measure of my joy within them.” The Word brings the disciples of Jesus a full measure of joy, but that same Word brings out the hatred of the world. No wonder He prays for their protection because those who have joy in the Word also have hatred from the world.
But He not only prayed for their protection, in vs. 17-19 Jesus prays for their sanctification, that they would be set apart from the world, that they would live lives of holiness, that they would be set apart for God’s use. I watched as my wife searched the cabinets for just the right foods to make lunch today. She set apart certain foods for her use in making lunch, so that she could bless the lives of others. And that is what Jesus wants of us; people who are set apart from their sin, set apart from the world to be used by Him in blessing the lives of others. And in His prayer He states the two ways we become sanctified, in vs. 17 it is through the Word, “sanctify them by the truth, your word is truth”, and in vs. 19 it is through the cross: “19 For them I sanctify myself, that they too may be truly sanctified.” He meant, “I die for their sin, so that they might die to their sin. I set myself apart to die for them, that they might die with me and live with me.” Sanctification comes through the Word and through the cross.
And now we come to vs. 20, and just like Jesus did in vs. 9 He clarifies Who He is praying for: 20 “My prayer is not for them alone (speaking about His 11 disciples). I pray also for those who will believe in me through their message.” He’s not praying only for the disciples who are with Him. No in His minds eye, He sees that the gospel would triumph despite the hatred of the world, and that millions of people down through the ages would read this Book and believe its message of forgiveness, and He prayed for them. He prayed for us. He saw the great harvest of believers who would believe the message. He saw the “travail of His soul”, that is the children of faith who would be born from His death for them. He saw the “spoils of the battle”, that is, people He would save and receive as the victory of His cross. He prayed for you and me. So please notice Jesus’ love for you here. He thought of you before you were born. He prayed for you before you came into existence. You were on His heart in John 17 as He prayed for you, and you were on His heart in John 19 as He died for you, and you were on His heart in John 20 as He rose for you, and you are on His heart as He ever lives to intercede for you. “My prayer is not for them alone. I pray also for those who will believe in me through their message.”
And what is His specific request for you and me, and for His church throughout all time? Look at vs. 21: “21 that all of them may be one, Father, just as you are in me and I am in you.” He prays for our unity, and He uses the example of the unity He has with His Father, so that the unity you and I are to have is to be a reflection of the unity Jesus and His Father have. Now imagine God the Father, God the Son and God the Holy Spirit, 3 in 1, and these 3 cannot be separated, they are 1 in essence and 1 in purpose, and that’s how you and I are to be. The only time that union was broken was through sin, as our sin was laid on Jesus He cried out My God my God why have you forsaken Me? Why is our unity broken? A division had come because of sin, and sin is the only thing that will ruin the unity of true believers.
Look with me at the Book of Ephesians. Ephesians chapter 2. And in Ephesians 2 Paul devotes a full half of a chapter to the subject of unity. It is an important topic, and Paul says in Ephesians 2:14: 14 For he himself is our peace, who has made the two one and has destroyed the barrier, the dividing wall of hostility, 15 by abolishing in his flesh the law with its commandments and regulations. His purpose was to create in himself one new man out of the two, thus making peace, Ephesians 2:14-15
Here Paul is taking two historical enemies, Jews and Gentiles and showing how Jesus made them one. See the Jews had God’s Law, the 10 commandments, and in their minds they were different from and better than those “Gentile dogs”, and that Law became a dividing wall of hostility. But when Jesus came He fulfilled all the requirements of the Law through His life, and He removed all the curses of the Law through His death, thereby He destroyed that dividing wall of hostility. Just like the Berlin Wall which was destroyed in 1990 united all of Germany, so Jesus destroyed the wall of hostility when He died. His purpose was to make the two one, to create unity and make peace.
But notice the rest of vs. 21: “May they also be in us so that the world may believe that you have sent me.” So I want us to consider the fact today that unity equals testimony. In other words, when we evidence that we are one in Christ, the world is powerfully affected. You know one of the reasons why the church at large is not more effective in reaching the lost today is because of divisions and splinter groups and denominations within the church. Back in 1990, America was involved in the Persian Gulf War. Troops took on the Iraqi forces out in the desert of Kuwait. In those two months, January and February, the USA won an outstanding victory, and had very few casualties. One of the interesting things about that war was that the majority of our troops weren’t injured or killed by the enemy. They were the victims of what is called “friendly fire”. Friendly fire is where you are hit by ammunition from your own troops. In other words, it’s where your own soldiers become your worst enemy. You can’t prepare for it, and you never see it coming. Right now in the church today, we have enemies from outside of us, but we also have enemies from within. The weapons that are used aren’t rifles and missiles. It’s our own words and attitudes. And Nonbelievers avoid some of our churches because they know they’ll be landing in the middle of a war zone. This should not be, when Jesus prayed for our unity to be a testimony to the world, and when Jesus died to make us one. That’s one reason why we are a non-denominational church. We do not take any other title on us than Christian, and we are one with Christians of all denominations.
You’ve probably heard it said that older couples who have been married a long time, and who have so much love for each other, can finish each other’s sentences. The church should be so united in heart and mind, and have so much love for each other, and be so focused on the gospel that we communicate as if we were one man. Has it ever occurred to you that one hundred pianos all tuned to the same fork are automatically tuned to each other? They are of one accord by being tuned, not to each other, but to another standard to which each of them submits. Just like that, you could take one hundred worshipers meeting together, and if each one is looking away to Jesus, they are one in heart. They are in tune with each other. And this is what testifies to the world. Who wants to go to a concert where all the instruments are out of tune? As Psalm 133:1 says, “1 How good and pleasant it is when brothers live together in unity!”
At the end of vs. 21 it says “so that the world will know that You have sent Me.” The world with all their divisions and selfishness and factions will see a totally different people if we are truly one in Christ.
22 I have given them the glory that you gave me, that they may be one as we are one: John 17:22
In the Old Testament, God says He will not share His glory with anyone, and yet Christians share in the glory of Jesus. In the Old Testament God did not live in people, the Holy Spirit would come on people but did not live in them, but in the New Testament God lives in us, and therefore we share His glory. The whole purpose of which is that we may be one.
But unity comes with maturity. Look with me at Ephesians 4 and let’s notice how unity is a by-product of maturity:
13 until we all reach unity in the faith and in the knowledge of the Son of God and become mature, attaining to the whole measure of the fullness of Christ. Ephesians 4:13
On the airplane on my way down to Houston last week there was a toddler sitting two rows back who was crying and shouting and demanding its own way. In a sense, that toddler sacrificed unity in the airplane to make sure everybody knew how it felt. And oftentimes immature Christians can sacrifice unity on the altar of their own feelings. Whereas, mature Christians have learned to make unity around Jesus essential. We aim for unity in faith, in our conversation, in our love for Jesus and for each other. This is the prayer of Jesus for us.
And just now I want us to notice something amazing, at the end of vs. 23: “23 I in them and you in me. May they be brought to complete unity to let the world know that you sent me and have loved them even as you have loved me.”
Is it not unbelievable to consider that God loves you and me just as God loves Jesus Christ? He loves Jesus as His Son, He loves us as His sons. He loves us just as He loves Jesus.
Well how does He love Jesus? I’m going to close with these three ways:
1. He loves Jesus dearly, as in Jesus is the very heart of God. Listen to what Ephesians 5:1 calls us: “1 Be imitators of God, therefore, as dearly loved children.”
2. He loves Jesus intimately. This intimacy is expressed in vs. 23 as He is speaking to His father He says, “You in me and I in you.” This is an intimate term, a passion term. The Father loves His Son with a holy passion, and the Father loves His sons with a holy passion. “For God so loved the world that He gave His One and only Son…” (John 3:16). 1 How great is the love the Father has lavished on us, that we should be called children of God!” 1 John 3:1 “10 This is love: not that we loved God, but that he loved us and sent his Son as an atoning sacrifice for our sins.” 1 John 4:10. He loves us intimately, just like He loves His Son.
3. He loves Jesus eternally. Look at the end of vs. 24: “24 …you loved me before the creation of the world.” Eph. 1 says He chose us before the creation of the world. Listen to Jeremiah 31:3 3 “”I have loved you with an everlasting love; I have drawn you with loving-kindness.” He loves us eternally, too.
He loves us dearly, He loves us intimately, and He loves us eternally. And when we are taken up in the love of God for us, and the love of Jesus in our hearts, we are one with each other. We are all tuned to the same tuning fork of Jesus and His love.
An American missionary was traveling across Korea by train. At a busy station an old man boarded and sat across from Him. The man was Korean and he addressed the American in his native tongue. The Missionary responded in the only Korean phrase that he knew which was “I don’t understand”. A few minutes later the Korean tried again, but the missionary could only say ” I DON’T UNDERSTAND” The Korean then tried a third question, and this time the American recognized a familiar word YESU which means JESUS. The American pointed to himself and said YESU, the Old man did the same thing with a smile of delight on His face. The Korean then took out a Bible, and he turned to a page and pointed to a place that he wanted the American to read. Remembering that oriental Bible are written from back to front, the missionary took his own Bible and counted the number of books and chapters from the back to the place that the old man had pointed to . The old man had pointed to Mark 3:35 “Whoever does the will of God is my brother.” The missionary immediately searched for a reply. He counted out and pointed to it in the Korean Bible. It was Psalm 133:1 “Behold how good and pleasant it is when brothers dwell in unity” The Korean man read it and smiled in agreement and for the rest of the journey, these two men, ages apart, cultures apart, countries apart, were brought together in an amazing friendship as they pointed first to one verse and then to another. Their separate Bibles had a common language of the Spirit, and brought an amazing unity.
Jesus prayed for our unity, Jesus died for our unity, let’s live our lives showing that God answered His prayer.
