I speak after the manner of men because of the infirmity of your flesh…
Standing altogether outside it, having no relation to it, destitute of it, entirely unaffected by it; strangers therefore to its happy and gainful service. Possessing a freedom which is a bane and a bondage. A planet's freedom from the law which preserves it in its orbit; a child's freedom from the restraints of a happy home. This freedom pleases the flesh, but ruins the man; it is not mercifully given, but madly taken; it is Satan's miserable choice, "Better to reign in hell than serve in heaven." Note the latent irony of the text; "Ye were free"; but what kind of freedom? A freedom akin to that of hell. Freedom from righteousness a man's greatest misery; freedom in righteousness his greatest mercy.
(T. Robinson, D. D.)

WEB: I speak in human terms because of the weakness of your flesh, for as you presented your members as servants to uncleanness and to wickedness upon wickedness, even so now present your members as servants to righteousness for sanctification.
