And yet God still acknowledges them in the OT.
I'm not sure what your point is.
Paul "acknowledged" the false goddess Artemis of the Ephesians.
Yes, Paul acknowledged that the Ephesians worshipped an idol, a non-existent God.
What exactly is that supposed to prove?
How does that contrast with Ps. 82, where Jesus cited the law to justify in calling himself the “Son of God”?
We've answered that about ten million times already.
Yet YOUR side continues to IGNORE Deut. 4:35,39, Deut. 32:39, 1 Kings 8:60, Ps. 86:10, Isa. 44:6,8, Isa. 45,21,22, Isa. 46:9, Mark 12:32, etc. etc.
