Question: where in the bible does it say in the blink of an eye?
Answer: 1 Corinthians 15:51-52 "Behold, I tell you a mystery: We shall not all sleep, but we shall all be changed-- in a moment, in the twinkling of an eye, at the last trumpet. For the trumpet will sound, and the dead will be raised incorruptible, and we shall be changed."
