Paul’s first letter to those in Corinth (a city about fifty miles west of Athens) was written around AD 55, and many of those who had seen the resurrected Jesus were still alive to share their testimony. The Christian faith was born in the time–space world that we occupy through a real person, Jesus Christ, and confirmed by eyewitnesses. This is one reason why the disciples were bold in their proclamation and, filled with the Holy Spirit (Acts 4:31), were ready to die for Jesus.
