33 And Peter answering said to him, 'Even if all shall be stumbled at thee, I will never be stumbled.' 34 Jesus said to him, 'Verily I say to thee, that, this night, before cock-crowing, thrice thou wilt deny me.' 35 Peter saith to him, 'Even if it may be necessary for me to die with thee, I will not deny thee;' in like manner also said all the disciples.

(Read Matthew 26:31-35)
Improper self-confidence, like that of Peter, is the first step to a fall. There is a proneness in all of us to be over-confident. But those fall soonest and foulest, who are the most confident in themselves. Those are least safe, who think themselves most secure. Satan is active to lead such astray; they are most off their guard: God leaves them to themselves, to humble them.
