Then why did God command the sculpting of cherubim on the Ark of the Covenant?
"And thou shalt make two cherubims of gold, of beaten work shalt thou make them, in the two ends of the mercy seat."
Sculptures like the Lincoln Memorial and the cherubim on the Ark are not intrinsically evil.
God forbids the worship of idols.
"They have been quick to turn away from what I commanded them and have made themselves an idol cast in the shape of a calf. They have bowed down to it and sacrificed to it and have said, 'These are your gods, Israel, who brought you up out of Egypt.'
Exodus 34:17
"Do not make any idols.
Leviticus 19:4
"'Do not turn to idols or make metal gods for yourselves. I am the LORD your God.
Leviticus 26:1
"'Do not make idols or set up an image or a sacred stone for yourselves, and do not place a carved stone in your land to bow down before it. I am the LORD your God.
You'll have to ask Him. Ours is not to question why . . .
