When Jesus prays he is already teaching us how to pray. His prayer to his Father is the theological path (the path of faith, hope, and charity) of our prayer to God. But the Gospel also gives us Jesus' explicit teaching on prayer. Like a wise teacher he takes hold of us where we are and leads us progressively toward the Father. Addressing the crowds following him, Jesus builds on what they already know of prayer from the Old Covenant and opens to them the newness of the coming Kingdom. Then he reveals this newness to them in parables. Finally, he will speak openly of the Father and the Holy Spirit to his disciples who will be the teachers of prayer in his Church.
