Listen and obey.
“You must not use gold or silver to make idols for yourselves; do not worship these gods in addition to me.
Make an altar of dirt for me, and sacrifice on it your whole burnt offerings and fellowship offerings, your sheep and your cattle.
Worship me in every place that I choose, and I will come and bless you. If you use stones to make an altar for me, don’t use stones that you have shaped with tools. When you use any tools on them, you make them unsuitable for use in worship.” – Exodus 20:23-26
“But Samuel answered, “What pleases the LORD more: burnt offerings and sacrifices or obedience to his voice? It is better to obey than to sacrifice. It is better to listen to God than to offer the fat of sheep.” – 1 Samuel 15:22
