Quote from : Morning and Evening, Based on the English Standard Version Book

If you will tell me when God permits a Christian to lay aside his armour, I will tell you when Satan has left off temptation. Like the old knights in war time, we must sleep with helmet and breastplate buckled on, for the arch-deceiver will seize our first unguarded hour to make us his prey. The Lord keep us watchful in all seasons, and give us a final escape from the jaw of the lion and the paw of the bear.
