Why do believers automatically fulfill the law once they are under grace?
Once a believer steps under grace, the Holy Spirit empowers them, and love becomes the whole motivating power behind everything they do; therefore they automatically fulfill the law. Love prevents stealing, false witness, gossip, and coveting, so the Ten Commandments' demands fall away rather than needing constant drilling.
Les explains that this is Paul writing to believers, and it is everyday practicality, not pie in the sky. Under grace believers do not need temple worship, a priesthood, animal sacrifices, or the Ten Commandments constantly drilled into them. Once they step under the light of grace and the Holy Spirit empowers them, love becomes the whole motivating power behind everything they do, so they automatically fulfill the Law. Les illustrates this by asking whether you can steal from someone you love, bear false witness or gossip about a loved one, or covet what a loved one owns. When love is operating, the Ten Commandments automatically fall away and no longer need constant teaching.
Owe no man any thing, but to love one another: for he that loveth another hath fulfilled the law.
