12 And having become clearly conscious [in himself], he came to the house of Mary, the mother of John who was surnamed Mark, where were many gathered together and praying. 13 And when he had knocked at the door of the entry, a maid came to listen, by name Rhoda; 14 and having recognised the voice of Peter, through joy did not open the entry, but running in, reported that Peter was standing before the entry. 15 And they said to her, Thou art mad. But she maintained that it was so. And they said, It is his angel. 16 But Peter continued knocking: and having opened, they saw him and were astonished.

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.
