Why is Abraham a model of prayer?

 Abraham listened to God. He was willing to set out for wherever God commanded and to do what God willed. By his listening and his readiness to make a new start, he is a model for our prayer.

Not many prayers of Abraham have been handed down. But wherever he went, he set up altars, places of prayer, to God. And so, along the journey of his life he had many sorts of experiences with God, including some that tried and unsettled him.
