12 Still shaking his head, amazed, he went to Mary's house, the Mary who was John Mark's mother. The house was packed with praying friends. 13 When he knocked on the door to the courtyard, a young woman named Rhoda came to see who it was. 14 But when she recognized his voice - Peter's voice! - she was so excited and eager to tell everyone Peter was there that she forgot to open the door and left him standing in the street. 15 But they wouldn't believe her, dismissing her, dismissing her report. "You're crazy," they said. She stuck by her story, insisting. They still wouldn't believe her and said, "It must be his angel." 16 All this time poor Peter was standing out in the street, knocking away.

Commentary on Acts 12:12-19
(Read Acts 12:12-19)
God's providence leaves room for the use of our prudence, though he has undertaken to perform and perfect what he has begun. These Christians continued in prayer for Peter, for they were truly in earnest. Thus men ought always to pray, and not to faint. As long as we are kept waiting for a mercy, we must continue praying for it. But sometimes that which we most earnestly wish for, we are most backward to believe. The Christian law of self-denial and of suffering for Christ, has not done away the natural law of caring for our own safety by lawful means. In times of public danger, all believers have God for their hiding-place; which is so secret, that the world cannot find them. Also, the instruments of persecution are themselves exposed to danger; the wrath of God hangs over all that engage in this hateful work. And the range of persecutors often vents itself on all in its way.
