The Apostle Paul testified the resurrected Christ appeared and was seen by Cephas or the Apostle Peter. This is the Peter who denied the Lord three times and yet the Lord was gracious to appear to him first. Jesus also appeared to the twelve disciples. It is proof of the resurrection by eye-witnesses. Jesus’ disciples testified of His resurrection. It is an eye-witness truth and is to be made known to the world. The resurrected Christ’s appearance to the disciples made them bold proclaimers of the truth of the resurrection from the Day of Pentecost.
