Acts 12:6

6.When he was about to bring him forth. It seemeth at the first blush that the Church prayeth to small purpose, for the day was now appointed wherein Peter should be put to death, and he is within one night of death, and yet the faithful cease not to pray, because they know that when the Lord doth purpose to deliver his, he taketh his time oftentimes in the last and farthest point of necessity, and that he hath in his hand diverse ways to deliver. Secondly, we may think that they did not so much pray for Peter’s life, as that the Lord would arm him with invincible fortitude, for the glory of the gospel, and that God would [not] set the gospel of his Son open to the reproaches and slanders of the wicked.

That night he slept. All these circumstances do more set forth the wonderful power of God, for who would not have thought that Peter was already swallowed up of death? for though he drew breath as yet, yet he had no chinch [chink] to creep out at, for as much as he was beset with many deaths. Therefore, whereas he escapeth from amidst deaths, whereas he goeth safely among the hands of his hangmen, whereas the chains are molten and are loosed, whereas the iron gate openeth itself to him; hereby it appeareth that it was a mere divine kind of deliverance, and it was profitable for Peter to be thus taught by these signs, that he might with more assurance forthwith declare unto men the grace of God thus known. Again, it appeareth by this strait keeping that Herod meant nothing less (757) than to let Peter go away alive.
