Everybody worships something or someone. We don't have a choice to be worshippers or not, we are built to worship and so we do. We all worship, the question is: what are you worshipping? Romans 1:21-24
21 For although they knew God, they did not honor him as God or give thanks to him, but they became futile in their thinking, and their foolish hearts were darkened. 22 Claiming to be wise, they became fools, 23 and exchanged the glory of the immortal God for images resembling mortal man and birds and animals and creeping things.24 Therefore God gave them up in the lusts of their hearts to impurity, to the dishonoring of their bodies among themselves, 25 because they exchanged the truth about God for a lie and worshiped and served the creature rather than the Creator, who is blessed forever! Amen.
We either worship God or something else. We either worship the Creator or something that he created! Idolatry is not (only) bowing down in front of a bronze statue, it is putting any created thing in the place of glory that belongs to the creator God. What do you spend your time, money and effort on. What do you think about, worry about, or daydream about most often? What person or thing are you willing to make sacrifices for? The answers will reveal your idols.
"Just" worship? We can't help it. Just check your heart for idols and worship God instead!
