Presumption is the crime of idolatry.

“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."  (1 Samuel 15: 22)

These are the words of the Prophet Samuel to the Saul, King of Israel.
Is there any area in your life where you believe that hard work, feeding the poor, sheltering the homeless, visiting the sick and the imprisoned is a good substitute to simple obedience to God's command?

God says that disobedience to a commandment like "Keep Holy the Lord's Day" is a rebellion as heinous as witchcraft or idolatry. (Cf 1 Samuel 15: 23).

"Not for your sacrifices do I rebuke you, your burnt offerings are always before me.....
You hate discipline; you cast my words behind you! (Psalm 50: 8, 17).

"The word of God is living and effective, able to discern reflections and thoughts of the heart." (Hebrews 4: 12).
