“Then Samuel said: Does the Lord take pleasure in burnt offerings and sacrifices as much as in obeying the Lord ? Look: to obey is better than sacrifice, to pay attention is better than the fat of rams.” 1 Samuel 15:22 CSB
Saul fell into a trap. He wanted to pick and choose when he could obey God, mostly based on what was most convenient for him. But Samuel would have none of that. No sacrifice or external accolades could ever cover over the sin of disobedience. Nope, you might be able to fool people, but you can never fool God.
Samuel’s response is a key passage of scripture. God is not mocked, and He does not want false, fake worship and hypocrisy. He does not want our praise, especially public praise, if we are not obedient to Him.
He wants obedience, not sacrifice.
Partial obedience is 100% disobedience. Before you worship, be sure to examine yourself, seeking God in every area of your life.
