12 When he realized this, he went to the house of Mary, the mother of John whose other name was Mark, where many were gathered together and were praying. 13 And when he knocked at the door of the gateway, a maid named Rhoda came to answer. 14 Recognizing Peter's voice, in her joy she did not open the gate but ran in and told that Peter was standing at the gate. 15 They said to her, "You are mad." But she insisted that it was so. They said, "It is his angel!" 16 But Peter continued knocking; and when they opened, they saw him and were amazed. 17 But motioning to them with his hand to be silent, he described to them how the Lord had brought him out of the prison. And he said, "Tell this to James and to the brethren." Then he departed and went to another place. 18 Now when day came, there was no small stir among the soldiers over what had become of Peter. 19 And when Herod had sought for him and could not find him, he examined the sentries and ordered that they should be put to death. Then he went down from Judea to Caesare'a, and remained there.

(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.
