John 17:9,10 - All mine are yours, and yours are mine

17:9

Jesus now states that He is praying for them, but not for the world. There is a distinction. Now we can certainly broaden the application of the prayer out, at least in some respect, to future believers, but there is a distinction between those who believe in the Son and those who do not. Jesus prays for us because we belong to the Father. Notice also that what is given to Jesus is immediately referred to as belonging to the Father.

17:10

As I have stressed many times, there is complete unity between the Father and the Son. All that the Son has belongs to the Father, and all that the Father has belongs to the Son. Here it is referring specifically to the people that belong to God.

ESV says Jesus is glorified in them, and NIV that glory has come to Jesus through them. ESV is probably the more accurate. The true wonder and glory of who Jesus is is shown through the church, in His people. The saving effect of Jesus is demonstrated in people. Eph 3:21 speaks of there being glory to Jesus in the church. Now when we look at the church we might question the validity of this verse, but there are several things that can be said. The first is that what the world counts as the church and what God counts as the church are not the same thing. Secondly, we need to realise what a high view God has of the church, and how great are His expectations and plans for the church.
