"But the angel of the Lord by night opened the prison doors, and brought them forth, and said,
Go, stand and speak in the temple to the people all the words of this life."
Doesn't the Lord do this for all of us at times? Whether the prison is physical, as here, or spiritual, he frees us and charges us to build Zion. We don't have time to be suffering for our mistakes, or sulking in a prison of our own making... we need to be out there helping others to succeed, and lifting their heads to see the world around them, and all the good they can do. Sometimes we are guilt-ridden and when the Lord opens the doors we think we should stay put and suffer anyway. :) ... but that is just some kind of backwards pride, thinking that Christ's atonement wasn't good enough for us or something. When God opens the doors, we should leap out, and start doing some good. :) Maybe it will keep us occupied enough that we don't get ourselves thrown back in. :)
