(1Co 15:2) “By which also ye are saved, if ye keep in memory what I preached unto you, unless ye have believed in vain.” One of the aspects, or results of salvation, is a resting (peace) in God’s promise of a resurrection. Though one cannot lose everlasting life (1Co_3:15 If any man’s work shall be burned, he shall suffer loss: but he himself shall be saved; yet so as by fire.), one can rob self of peace of soul.
