“Because when they knew and recognized Him as God, they did not honor and glorify Him as God or give Him thanks, but instead they became futile and godless in their thinking (with vain imaginings, foolish reasoning, and stupid speculations) and their senseless minds were darkened.” Romans 1:21 (Amplified)
So what happens when you ignore God and act like He doesn’t exist? Well this verse says your mind is darkened. I suppose it might compare to walking outside into the sunlight, when you move toward God, but walking into a darkened room or closet, when you turn from Him. The latter doesn’t sound like a very pleasant place to me, which do you choose?
All of creation honors and glorifies God every day when birds sing, flowers bloom and rainbows appear in the sky. Let us do the same so that our minds will not become darkened.
