What does Jesus' prayer (Luke 10:21-22) tell us about God and about ourselves?

First, it tells us that God is both Father and Lord of earth as well as heaven. He is both Creator and Author of all that he has made, the first origin of everything and transcendent authority, and at the same time, goodness and loving care for all his children. All fatherhood and motherhood are derived from him (Ephesians 3:14-15). Jesus' prayer also contains a warning that pride can keep us from the love and knowledge of God.

All things have been handed over to me by my Father, and no one knows who the Son is except the Father, or who the Father is except the Son and anyone to whom the Son chooses to reveal him.”
