“We which are alive and remain unto the coming of the Lord shall not prevent them which are asleep. For the Lord himself shall descend from heaven, ... and the dead in Christ shall rise first: then we which are alive and remain shall be caught up together with them in the clouds” (1 Thes., iv, 15–17).
Paul believed that Christ had appeared to him. It was a delusion. He expected Christ to come again. He was mistaken.
