Ungodly thinkers often are right in their conclusions because God reveals reality to them just as He reveals reality to every person. However, they refuse to give Him glory or to acknowledge Him for His gift to them. And we understand that when God says He reveals Himself to every person, He includes those who resist Him. ^{(Romans 1:19-20)} So, even those who resist Him have revelation of right and wrong, yet they refuse to acknowledge God because they love darkness rather than light. ^{(John 3:19)} God reveals right and wrong to them, but they can only react pragmatically to what God reveals since they refuse to acknowledge God. They refuse to acknowledge the source of knowledge, so they don’t distinguish between what God reveals and what brute-beast minds fabricate. And because they don’t want to worship God or serve Him, God turns them over to their own reprobate minds. ^{(Romans 1:28)} They also know that they’ll receive judgment for the things they do, and yet they do them. ^{(Romans 1:30)}
