31 On the way, Jesus told them, "Tonight all of you will desert me. For the Scriptures say, 'God will strike the Shepherd, and the sheep of the flock will be scattered.' 32 But after I have been raised from the dead, I will go ahead of you to Galilee and meet you there." 33 Peter declared, "Even if everyone else deserts you, I will never desert you." 34 Jesus replied, "I tell you the truth, Peter-this very night, before the rooster crows, you will deny three times that you even know me." 35 "No!" Peter insisted. "Even if I have to die with you, I will never deny you!" And all the other disciples vowed the same.

(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.
