7. A light shined, It is to be thought that Peter alone saw this light, and that the soldiers did either sleep so soundly, or else were so amazed, that they neither felt nor perceived any thing, And there might be two causes why God would have the light to shine; either that Peter might have the use thereof, and that the darkness might be no hindrance to him, or that it might be to him a sign and token of the heavenly glory. For we read oftentimes that the angels appeared with glistering brightness, even when the sun did shine, Assuredly, Peter might have gathered by the strange light that God was present, and also he ought to have made his profit thereof. When as the angel smiteth Peter’s side, it appeareth hereby what a care God hath for his, who watcheth over them when they sleep, and raiseth them when they are drowsy. And surely there were nothing more miserable than we, if the continuance of our prayers alone did keep God in his watching over us; for such is the infirmity of our flesh that we faint and quail, and we stand most of all in need of his help when our minds, being drawn away, do not seek him. Sleep is a certain image of death, and doth choke and drown all the senses, what should become of us if God should then cease to have respect to us? But forasmuch as when the faithful go to sleep, they commit their safety to God, it cometh to pass by this means, that even their sleep doth call upon God.
Whereas he saith, that immediately after the angel had said the word the chains were loosed, we gather by this, that there is power enough in the commandment of God alone to remove all manner [of] lets, when all ways seem to be stopt on all sides, so that if he intend to appease the motions and tumults of war, although the whole world were appointed in armor, their spears and swords shall forthwith fall out of their hands; on the other side, if he be determined to punish us and our sins with war, in a moment, (in the twinkling of an eye,) their minds, which were before given to peace, shall wax hot, and they shall lay hand on their swords. Whereas Luke setteth down severally both the words of the angel, and also the course of the matter, it serveth for the more certainty of the history, that it may in every respect appear that Peter was delivered by God.
