“For if ye live after the flesh, ye shall die: but if ye through the Spirit do mortify the deeds of the body, ye shall live.”
King James Version (KJV)
8:13 The deeds of the flesh - Not only evil actions, but evil desires, tempers, thoughts. If ye mortify - Kill, destroy these. Ye shall live - The life of faith more abundantly here, and hereafter the life of glory.
Ro 8:13 But if ye through the Spirit. By following the Spirit, "minding the things of the Spirit" (Ro 8:5), we secure life. This is shown in Ro 8:11. The deeds of the body are the sinful deeds suggested by the fleshly desires. We cannot in our own strength "mortify", i.e., put an end to, "the deeds of the body". It is accomplished by the aid of the Spirit, helping our spirit in the effort.
