“As long as I’m worshiping God, do I need to be all that concerned about the exact mechanics or details of how I do it? He is pleased, as long as my heart and intent are set on Him, right?”
God sent the prophet Amos to the northern kingdom of Israel about 30 years before they fell to Assyria. He warned about the impending judgment and told of the captivity awaiting them. One of the issues raised by the Lord was their worship. Contemplate God saying this to His people who were (supposedly) worshiping Him: “I hate, I despise your feast days, And I do not savor your sacred assemblies. Though you offer Me burnt offerings and your grain offerings, I will not accept them, Nor will I regard your fattened peace offerings. Take away from Me the noise of your songs…” (Amos 5:21-23). God had commanded their feast days, assemblies, offerings and singing, but what they were now doing (with those things) was detestable to Him!
The manner in which we worship must align faithfully with the “truth” of God’s word in order to be acceptable to Him!
