Love does no harm to a neighbor; therefore love is the fulfillment of the law. (Romans 13:10, NKJV)
Love obeys God’s law. By doing so it fulfills law. It is indeed futile to try to separate our obedience to God’s law and our love for Him and for our neighbors. Obeying God’s commands grows out of loving God with all your heart, soul, mind, and strength (Mark 12:30). Loving your neighbor means loving him as you love yourself (Mark 12:31). Just as we do not seek to harm ourselves, love does no harm to its neighbor. Love does not commit adultery, does not murder, does not steal, does not bear false witness, does not covet, or do anything else that harms another person (Romans 13:8-9). Love actively does good instead of evil. Obeying the will of God from the heart is love in action (Romans 6:17; 1 John 3:17-18). Love is not set in contrast to obeying the law of God; It is not one or the other. Instead, love actively fulfills (accomplishes, obeys) the law of God.
