69 Now Peter was sitting outside in the court, and a maid came to him, saying, “You were also with Jesus, the Galilean!” 70 But he denied it before them all, saying, “I don’t know what you are talking about.” 71 When he had gone out onto the porch, someone else saw him, and said to those who were there, “This man also was with Jesus of Nazareth.” 72 Again he denied it with an oath, “I don’t know the man.” 73 After a little while those who stood by came and said to Peter, “Surely you are also one of them, for your speech makes you known.” 74 Then he began to curse and to swear, “I don’t know the man!”
Immediately the rooster crowed. 75 Peter remembered the word which Jesus had said to him, “Before the rooster crows, you will deny me three times.” He went out and wept bitterly.

(Read Matthew 26:69-75)
Peter's sin is truly related, for the Scriptures deal faithfully. Bad company leads to sin: those who needlessly thrust themselves into it, may expect to be tempted and insnared, as Peter. They scarcely can come out of such company without guilt or grief, or both. It is a great fault to be shy of Christ; and to dissemble our knowledge of him, when we are called to own him, is, in effect, to deny him. Peter's sin was aggravated; but he fell into the sin by surprise, not as Judas, with design. But conscience should be to us as the crowing of the cock, to put us in mind of the sins we had forgotten. Peter was thus left to fall, to abate his self-confidence, and render him more modest, humble, compassionate, and useful to others. The event has taught believers many things ever since, and if infidels, Pharisees, and hypocrites stumble at it or abuse it, it is at their peril. Little do we know how we should act in very difficult situations, if we were left to ourselves. Let him, therefore, that thinketh he standeth, take heed lest he fall; let us all distrust our own hearts, and rely wholly on the Lord. Peter wept bitterly. Sorrow for sin must not be slight, but great and deep. Peter, who wept so bitterly for denying Christ, never denied him again, but confessed him often in the face of danger. True repentance for any sin will be shown by the contrary grace and duty; that is a sign of our sorrowing not only bitterly, but sincerely.
