“I do not ask for these only, but also for those who will believe in me through their word, 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.
John 17:20-21 ESV

There is obviously so much in this chapter to comment on. So much depth in these forces one could write a book per chapter.
However something specifically set out to me. In verses 20 and 21. Jesus is praying and says not only for these (apostles and disciples) but for all those that believe in me. Meaning that even I thousands of years later will receive the Holy Spirit and the father’s blessings just as the apostles did. And when I die I will dwell with them as equals.
That all men are equal in Christ. Which is scary because that means that also if you are not in Christ you are also all equally not going to go out with him and the father.
