The core of Christ's prayer isn't just about believers getting along, but about them sharing a vital, life-giving union with the Father and Son. This profound internal unity, mirroring the Godhead, is what's meant to be so radically evident that it compels the "world" to believe.
that they may all be one, just as you, Father, are in me, and I in you, that they also may be in us, so that the world may believe that you have sent me. The glory that you have given me I have given to them, that they may be one even as we are one,
English Standard Version (ESV)
Jesus has just finished praying specifically for the apostles and now broadens His prayer to include all future believers. He asks that they be unified, mirroring the inseparable, vital union between Himself and the Father, so that this profound unity among His followers will serve as compelling evidence to the world of His divine mission.
What if Christian unity isn't just a nice idea, but a divine necessity? Jesus Himself prayed for it, modeling it after His own perfect relationship with the Father.
Jesus' prayer in John 17 isn't just a wish list; it's a blueprint. He prays, "that they may all be one." This isn't a call for mere cooperation or agreement, but a deep, shared life. The comparison Jesus uses – "just as you, Father, are in me, and I in you" – points to a unity that mirrors the inseparable, life-giving communion within the Trinity itself.
This divine unity is meant to be lived out by believers:
Imagine a world so captivated by your love and unity that it's compelled to believe in Jesus. That's the power Jesus is talking about.
Jesus' ultimate goal for Christian unity isn't just for our own comfort or a strong church community. It's a strategic mission to reach the world. He states it clearly: "so that the world may believe that you have sent me."
