Habakkuk 2:18 “What profit is the image, that its maker should carve it, the moulded image, a teacher of lies, that the maker of its mould should trust in it, to make mute idols?
Buying in to something that someone else is proclaiming to be god is just as bad as making something up yourself; only that you are trusting in someone else’s lie instead of your own.
Making an idol is a lie. You cannot make gods. Believing someone else can make gods is just as bad.
But we all do lift up many things in our lives all the time! We lift up people, we lift up man made things, we lift up ideas… and we look to them instead of looking to God at times… which makes them idols!
