(a) Romans 8:13 if ye live after the flesh, ye shall die; "For  to  be carnally minded [is] death; but  to  be  spiritually minded [is] life and peace." (Romans 8:6)
"For he that soweth to his flesh shall of the flesh reap  corruption;  but he that soweth to the Spirit shall of the Spirit  reap life everlasting." (Galatians 6:8)
