“Then Peter stepped forward with the eleven other apostles and shouted to the crowd” (Acts 2:14 NLT).

FROM FEARFUL DENIER TO BOLD PREACHER
When Jesus was arrested and taken to the high priest’s house for questioning, Peter denied three times that he even knew Jesus. Yet, fifty days later, after witnessing the risen Lord Jesus and seeing His ascension into heaven, Peter and 120 other believers received the Holy Spirit on the day of Pentecost. It was on that day that Simon Peter finally became the “rock” (Greek “Petros” means “rock”), which the name Jesus had given him implied. For Peter went from fearfully denying Jesus in the dark to boldly proclaiming Him in the light of day.
