Matthew Poole and continuators on Romans 6:13

13 Neither yeild ye your members as instruments of unrighteousness unto sin, but yeild your selves unto God, as those that are alive from the dead ; and your members as instruments of righteousness unto God.

He fitly compares our bodily members to Tools that Artificers work, or weapons that Souldiers fight withall; for as those, so these may be used well or ill, e. g. with the hand one man giveth an almes, another stealeth; with the tongue one man blesseth, another curseth. By members here we are not only to understand the parts of the body▪ as the Hands, Eyes, Ears▪ &c. But also the Faculties of the soul, as the Understanding, Will, Affections, &c. These bear some proportion to the bodily members, as the Understanding to the Eye, &c. All of them must be employed by us, as Weapons to fight, not under the command of Satan for Sin, but under the command of God for Righteousness.

These words contain a reason, why we should not serve Sin and Satan, but bequeath and dedicate our selves to the service of God, because we are indued with a Spiritual Life, after a Spiritual Death; or because we have received so great a benefit as to be raised in Christ from the death and power of sin.
