John 18:27
Peter then denied again; and immediately the cock crew.
Peter had really “blown it” this time. After promising allegiance to his Lord he now had denied Him three times. The crowing of the rooster served only to remind him that the Lord said this would happen. Peter was through, finished, washed up, right? Wrong! The Lord restored Peter and gave him a great work to do. Confess your faults (and your sins), ask for His help, and DON’T GIVE UP.
