1. "I am in the Father, the Father is in me." (7-11)
We long to come to know God in a deep and personal way. But this seems impossible, because God is spirit. Jesus teaches here that we can come to know God when we come to know Jesus. How can we know the Father by knowing Jesus? Because Jesus is in the Father and the Father is in Jesus. Jesus is the physical manifestation of God Himself. We can come to know God the Father when we listen to Jesus' words, for that is God speaking. We can know the Father by Jesus' works. He came and lived and died so that we may know God the Father.
2. We will do even greater things than these (12-14)
Because we know the Father through Jesus we also can do two things. We can do great works. Jesus promises when we do his work, we will do even greater things than he!. We can take the gospel to the ends of the earth to all people. Secondly, we can ask the Father for anything in Jesus' name, that God may be glorified in Jesus.
