Jesus’ high priestly prayer in John 17 serves as a pattern of His intercession that He carries on for us in heaven now. It also serves as an example for our own prayer life. In a nutshell, what Christ asks for us, we should ask for ourselves.
“Jesus here shows teachers an example, that they should not only occupy themselves in sowing the Word, but, by mixing their prayers with it, should implore God’s help that his blessing should make their work fruitful.” – John Calvin
“It is in prayer, costly, sustained, and prevailing, that the Word of God is released through teaching and preaching. Prayer is the price of power, and the church of Jesus Christ is not likely to recover its lost authority until this basic biblical truth is recovered.” – John Milne’s commentary on John 17
