When we were in Dublin, I went out one morning to an early meeting, and I found the servants had not opened the front door. So I pulled back a bolt, but I could not get the door open. Then I turned the key, but the door would not open. Then I found there was another bolt at the top, then I found there was another bolt at the bottom. Still the door would not open. Then I found there was a bar, and then I found a night-lock. I found there were five or six different fastenings. I am afraid that door represents every sinner's heart. The door of his heart is locked, double-bolted, and barred. (D. L. Moody.)
