God requires obedience
For I desire mercy and not sacrifice, And the knowledge of God more than burnt offerings.
The sacrifices of God are a broken spirit, A broken and a contrite heart—These, O God, You will not despise.
To do righteousness and justice Is more acceptable to the LORD than sacrifice. (Proverb 21:3)
But go and learnt what this means: 'I DESIRE MERCY AND NOT SACRIFICE.' For I did not come to call the righteous, but sinners, to repentance. (Matthew 9:13)
"Now by this we know that we know Him, if we keep His commandments. (1John 2:3)
