I Corinthians 50-52 Now this I say, brethren, that flesh and blood will not inherit the kingdom of God; nor does corruption inherit incorruption. Behold, I tell you a mystery: We shall not sleep, but we shall 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.
