17 But God be thanked that though you were slaves of sin, yet you obeyed from the heart that form of doctrine to which you were delivered. 18 And having been set free from sin, you became slaves of righteousness. (Romans 6:17–18, NKJV)
Obedience to God springs from the heart. Otherwise, it is not obedience at all, only an empty shell of pretense, self-righteousness, and vain ritual (Matt. 6:1-18; Lk. 18:9-14; 6:46). Today’s passage explains we are set free from sin when we obey the gospel (“that form of doctrine”) from the heart. Unquestionably, obedience is essential for salvation from sin. Now, back to the heart and our obedience. Scripture teaches the heart is the source of obedience to God. Belief is the result of the word of God acting upon the heart, and without faith, obedience does not occur (Rom. 10:10, 16-17). Love is an action of the heart (will) that Scripture shows to be obedience, “For this is the love of God, that we keep His commandments” (1 Jno. 5:4). Love itself is obedience to God. Without the heart, obedient love is impossible. The fear of God resides in the heart that keeps God’s commandments (Eccl. 12:13). Faith, love, and the fear of God spring from the heart as necessary traits of obedience. Do not try to separate your heart from your obedience. Every attempt to do so results in faithless, loveless, irreverent, and futile attempts to please God.
