Amos 5:21–27 (NKJV)
21 “I hate, I despise your feast days, and I do not savor your sacred assemblies.
22 Though you offer Me burnt offerings and your grain offerings, I will not accept them, nor will I regard your fattened peace offerings.
23 Take away from Me the noise of your songs, for I will not hear the melody of your stringed instruments.
24 But let justice run down like water, and righteousness like a mighty stream.
25 “Did you offer Me sacrifices and offerings in the wilderness forty years, O house of Israel?
26 You also carried Sikkuth your king and Chiun, your idols, the star of your gods, which you made for yourselves.
27 Therefore I will send you into captivity beyond Damascus,” says the Lord, whose name is the God of hosts.
In this continued discussion of the Day of the Lord, we see the things that make God sick. The Northern Kingdom’s feasts, the nations sacrifices to God, and the worship of all His people. Why do these make Him sick? Because Israel mixed the worship of Yahweh with the cultic worship of idols! When a Christian lives in a way that seems to worship God, but also gives tremendous place in their lives to non-Christian influences, it is just as idolatrous as the Israelites offering sacrifices to God, and then worshipping an idol in their house. Don’t be divided, but give God your all!
