Love must be sincere. Detest what is evil; cling to what is good.
We must first give ourselves to the Lord, this is the spring of all obedience. Present your bodies, your whole selves, as living sacrifices; it is by laying your hand on the offering and transferring all your right and interest to God that the sacrifice takes hold. Though he could command with authority, the apostle beseeches us instead, for men are more easily led than driven.

Commenting on Romans 12:1-21
Verse 9. Let love. The apostle proceeds to specify the duties of Christians in general, that they might secure the beauty and order of the church. The first which he specifies is love. This word here evidently refers to benevolence, or to good-will toward all mankind.
9. Let love be, etc. Proceeding now to speak of particular duties, he fitly begins with love, which is the bond of perfection. And respecting this he enjoins what is especially necessary, that all disguises are to be cast aside, and that love is to arise from pure sincerity of mind.
