Unless he obeys, a man cannot love.
"...What is more pleasing to the LORD: your burnt offerings and sacrifices or your obedience to His voice? Listen! Obedience is better than sacrifice, and submission is better than offering the fat of rams." (1Sa 15:22, NLT).
The Message Bible beautifully paraphrases, "... Do you think all GOD wants are sacrifices-- empty rituals just for show? He wants you to listen to him! Plain listening is the thing, not staging a lavish religious production." (1Sa 15:22, MSG).
I love in obedience based on love for the Lord, not based on rules and regulations done in a religious way. God hates religion but loves relationship.
