Jesus had told Peter earlier in the evening, whilst they were eating together with the other disciples, that he would deny knowing him. He predicted that Peter would do this three times that night, before the rooster crowed at dawn. Peter had been quite upset and had told Jesus, that he would never do that. Peter had bravely followed Jesus as he was arrested and taken to the High Priest’s house. The other disciples ran away when the guards arrived in the garden. As Peter tries to blend in, he is asked whether he knows Jesus, afraid and wanting to be invisible he does exactly what he said he would not do. Christians believe that when you pretend to not be someone’s friend, because you are scared, Jesus forgives you.
