Acts 12:8

And the angel said unto him, Gird thyself, and bind on thy sandals. And he did so. And he saith unto him, Cast thy garment about thee, and follow me.

And he did so ... Peter's response to God's message was exactly what it should have been. If the apostle had been like many today who are commanded to obey the word of God, he might have said, "Sh-sh-sh, Angel, don't wake up the guard!" Or he might have said, "Well, thanks, Angel, I'll think about it! Some other time, I just might do what you say." Still another possible response was, "Well, Angel, I won't promise you anything. You know how it is. I'd like to get out of here all right; but you know we might wake somebody up, and that would be bad. The jailer would not like that!" Are not the excuses which men make ridiculous?

(5) The fifth thing that entered into Peter's deliverance was the falling off of his chains. They fell off when he rose to obey the word of the angel. The application is in this, that men's chains of sin will fall off when they arise and are baptized into Christ; and they will never fall off until this is done.

(6) Then Peter followed the angel. See next verse.
