“I am praying not only for these disciples but also for all who will ever believe in me through their message. I pray that they will all be one, just as you and I are one—as you are in me, Father, and I am in you. And may they be in us so that the world will believe you sent me. I have given them the glory you gave me, so they may be one as we are one. I am in them and you are in me. May they experience such perfect unity that the world will know that you sent me and that you love them as much as you love me. Father, I want these whom you have given me to be with me where I am. Then they can see all the glory you gave me because you loved me even before the world began! (John 17:20-24)
To be in Christ and He in you is more than just being in agreement. It’s your spirit made alive by being merged with his Spirit.
