Read John 17:20-26
20 “I pray not only for them, but also for those who believe in me because of their message. 21I pray that they may all be one. Father! May they be in us, just as you are in me and I am in you. May they be one, so that the world will believe that you sent me. 22I gave them the same glory you gave me, so that they may be one, just as you and I are one: 23I in them and you in me, so that they may be completely one, in order that the world may know that you sent me and that you love them as you love me.
24 “Father! You have given them to me, and I want them to be with me where I am, so that they may see my glory, the glory you gave me; for you loved me before the world was made. 25Righteous Father! The world does not know you, but I know you, and these know that you sent me. 26I made you known to them, and I will continue to do so, in order that the love you have for me may be in them, and so that I also may be in them.”
Jesus prays for unity in the church; he prays that the church would reveal his glory to the world.
