As surely as Peter believed he would die
Paul was convinced he would be remain alive at the coming of the Lord.
*[[2Pe 1:14]] KJV* Knowing that shortly I must put off this my tabernacle, even as our Lord Jesus Christ hath shewed me.
*[[1Th 4:17]] KJV* Then we which are alive and remain shall be caught up together with them in the clouds, to meet the Lord in the air: and so shall we ever be with the Lord.
