33 But Peter made answer and said to him, Though all may be turned away from you, I will never be turned away. 34 Jesus said to him, Truly I say to you that this night, before the hour of the cock's cry, you will say three times that you have no knowledge of me. 35 Peter says to him, Even if I am put to death with you, I will not be false to you. So 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.
