What does Matthew 26:75 mean?
An unpleasant realization has come back to Peter in a rush, in a single moment. Christ had told Peter he would deny Jesus three times before the rooster crowed (Matthew 26:30–35). Peter had boldly and brashly declared that he would die with Jesus before such a thing could happen. He'd wielded a sword in a misguided attempt to prevent Jesus' arrest (Matthew 26:51; John 18:10). Now the rooster had called out and Peter is painfully aware of his denials: three, just as Jesus had said.Peter had the chance to follow through on his earlier pledge of loyalty. He was in the courtyard of the home where Jesus was condemned to die, where Jesus was being beaten (Matthew 26:64–69). All Peter had to do was admit that, yes, he was one of Jesus' disciples. He could declare he did in fact believe that Jesus was the Messiah, the Christ, the Son of the living God (Matthew 16:15–17). That would have been honest, even if it might have resulted in being taken for death, rather than denying the Lord.
Peter finally got away from danger after his third denial. This is not a clean escape, however. The crushing weight of his own disloyalty, cowardice, and lies is crashing down around him. Eventually, Peter will come to know that Jesus did not want him to die that night (John 18:8). He would experience Jesus' forgiveness and learn that he would one day die for Jesus, after all (John 21:18–19). Tonight, though, Peter would suffer in knowing that he was not as strong in himself as he thought he was. He would need that humility to carry out what God had next for him in the coming weeks, months, and years.
