Isaiah 44:18-20. “They have not known nor understood: for He hath shut their eyes, that they cannot see; and their hearts, that they cannot understand. And none considereth in his heart, neither is there knowledge, nor understanding to say, I have burned part of it in the fire; yea, also I have baked bread upon the coals thereof: I have roasted flesh and eaten it; and shall I make the residue thereof an abomination? shall I fall down to the stock of a tree? He feedeth on ashes; a deceived heart hath hath turned him aside, that he cannot deliver his soul, nor say, Is there not a lie in my right hand?”
When you really stop and think about it, the absurdity of using the same tree for warmth, for cooking, and for making idols just doesn’t make any sense. People are literally falling down before the stock of a tree. Feeding on ashes. Creating that which they can worship, because they have blind hearts and eyes and cannot–will not–see God.
