In this sermon Escape From "Lock-Up", Peter's imprisonment hindered Peter from doing his ministry for the Lord.  If there is anyone here who is hindered from doing the will of the Lord, it is because you are spiritually imprisoned. You may not be physically in a prison cell, like Peter was, but you are imprisoned. Whatever LOCKED YOU UP, figuratively speaking, is hindering you from doing your work for God and is therefore become your prison. If you can only get past your thinking that gets messed up and your flesh that is like an iron gate in these times, so far as your ministry is concerned, you will get out into the street where the action is and do your ministry.
