In Saul's conversion, great things were asked of him, but it could not have happened if people along the road did not stop and take him to Ananias. God calls us to great things and to small, hidden things as well. It is all part of God's great plan.
King David wants to build a temple for the Lord, and the Lord says "No!" because David wanted to pretend that he should provide for God, ignoring the fact that God has always provided for him. We need to trust that God provides what we need, and sometimes God's "no" to our prayers is a reminder of this.
Br. Joe Trout, OP breaks open the readings for the Third Sunday of Ordinary Time, pointing out how Jesus, Paul, and Jonah all preach a message of urgent repentance. These messages were headed in different ways in different situations, but people reformed their lives. Will we?
