Was John 17 a Pipe Dream?

 There may be a lot of organizational differences among Protestants, and that is frequently attacked. However, when it comes to the belief that we are saved by Christ's atoning death on the cross and His resurrection, we're all unified. We are one body in Christ through the unifying Holy Spirit. That unity is a fact. John 17:20-23 was not a vain hope of Christ. Stop looking at the outward appearances and look at the inner man and woman. There is more unity than the world realizes. 

Jesus Prays for All Believers

^{John 17: 20} “My prayer is not for them alone. I pray also for those who will believe in me through their message, ²¹ that all of them may be one, Father, just as you are in me and I am in you. May they also be in us so that the world may believe that you have sent me. ²² I have given them the glory that you gave me, that they may be one as we are one— ²³ I in them and you in me—so that they may be brought to complete unity. Then the world will know that you sent me and have loved them even as you have loved me.
