If we are in any of these prisons

(J. R. Miller, "Paul's Message for Today" 1904)

"Suddenly there was such a violent earthquake
 that the foundations of the prison were shaken.
 At once all the prison doors flew open, and
 everybody's chains fell off!" Acts 16:26

There is no prison too strong for God to break open;
there are no chains too heavy for Him to snap asunder,
there are no walls too thick for Him to shatter.

There are other kinds of prisons besides those built
with stone—prisons of trial, of temptation, of trouble,
of circumstances. If we are in any of these prisons,
God is just as able to bring us out of them!
