33 But Peter answered and said unto him, If all shall be offended in thee, I will never be offended. 34 Jesus said unto him, Verily I say unto thee, that this night, before the cock crow, thou shalt deny me thrice. 35 Peter saith unto him, Even if I must die with thee, [yet] will I not deny thee. Likewise also said all the disciples.

Commentary on Matthew 26:31-35
(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.
