1 Samuel 15:22 MSG

[22] Then Samuel said, 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. Not doing what God tells you is far worse than fooling around in the occult. Getting self-important around God is far worse than making deals with your dead ancestors. Because you said No to God’s command, he says No to your kingship.
