“I hate, I despise your religious feasts; I cannot stand your assemblies. Even though you bring me burnt offerings and grain offerings, I will not accept them. Though you bring choice fellowship offerings, I will have no regard for them. Away with the noise of your songs! I will not listen to the music of your harps.” – Amos 5:21-23
What would make God so angry?
“You trample on the poor and force him to give you grain. Therefore, though you have built stone mansions, you will not live in them; though you have planted lush vineyards, you will not drink their wine. For I know how many are your offenses and how great your sins. You oppress the righteous and take bribes and you deprive the poor of justice in the courts.” – Amos 5:11-12
What kind of worship does God desire?
“But let justice roll on like a river, righteousness like a never-failing stream!” – Amos 5:24
