6 The very night before Herod was going to bring him out, Peter, bound with two chains, was sleeping between two soldiers, while guards in front of the door were keeping watch over the prison. 7 Suddenly an angel of the Lord appeared and a light shone in the cell. He tapped Peter on the side and woke him, saying, "Get up quickly." And the chains fell off his wrists. 8 The angel said to him, "Fasten your belt and put on your sandals." He did so. Then he said to him, "Wrap your cloak around you and follow me." 9 Peter went out and followed him; he did not realize that what was happening with the angel's help was real; he thought he was seeing a vision. 10 After they had passed the first and the second guard, they came before the iron gate leading into the city. It opened for them of its own accord, and they went outside and walked along a lane, when suddenly the angel left him. 11 Then Peter came to himself and said, "Now I am sure that the Lord has sent his angel and rescued me from the hands of Herod and from all that the Jewish people were expecting." 12 As soon as he realized this, he went to the house of Mary, the mother of John whose other name was Mark, where many had gathered and were praying. 13 When he knocked at the outer gate, a maid named Rhoda came to answer. 14 On recognizing Peter's voice, she was so overjoyed that, instead of opening the gate, she ran in and announced that Peter was standing at the gate. 15 They said to her, "You are out of your mind!" But she insisted that it was so. They said, "It is his angel." 16 Meanwhile Peter continued knocking; and when they opened the gate, they saw him and were amazed. 17 He motioned to them with his hand to be silent, and described for them how the Lord had brought him out of the prison. And he added, "Tell this to James and to the believers." Then he left and went to another place.

(Read Acts 12:6-11)
A peaceful conscience, a lively hope, and the consolations of the Holy Spirit, can keep men calm in the full prospect of death; even those very persons who have been most distracted with terrors on that account. God's time to help, is when things are brought to the last extremity. Peter was assured that the Lord would cause this trial to end in the way that should be most for his glory. Those who are delivered out of spiritual imprisonment must follow their Deliverer, like the Israelites when they went out of the house of bondage. They knew not whither they went, but knew whom they followed. When God will work salvation for his people, all difficulties in their way will be overcome, even gates of iron are made to open of their own accord. This deliverance of Peter represents our redemption by Christ, which not only proclaims liberty to the captives, but brings them out of the prison-house. Peter, when he recollected himself, perceived what great things God had done for him. Thus souls delivered out of spiritual bondage, are not at first aware what God has wrought in them; many have the truth of grace, that want evidence of it. But when the Comforter comes, whom the Father will send, sooner or later, he will let them know what a blessed change is wrought.
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.
