Ephesians: When I consider “prisoner for the Lord” I think more in terms of surrender. Whenever lives are not our own whose are they? They are Christ’s. One can be a prisoner to sin and death or one can be a prisoner for Christ which is a prisoner to life. John MacArthur’s take (which I will yield is probably more accurate) is that as Paul wrote Ephesians he was in Rome likely under house arrest. MacArthur’s point is to serve as a reminder that as Christians, we may be called on to be imprisoned or even to die for Christ.
