What you stated was your bias on what I said
Maybe it was just my misunderstanding from not paying close enough attention. My apology and I stand corrected if I have misquoted you.
The problem with fallen man isn't that he can't understand the Bible and the gospel and what is required of him. He knows this through creation and conscience. The problem is that knowing these things, he doesn't glorify God nor is thankful towards Him...Romans 1. So, the question is why?
Perhaps you know the answer to this. Do you?
I think you're mixing 2 different pieces of spiritual information. Romans 1 speaks of God's existence, His eternal power, His divinity. and His judgment known through Creation and conscience.
The Good News of His Son is not the same thing identified in mid to end of Romans 1 and shortly beyond.
But what I understand you to be saying is that fallen man can understand what is required of him, including the Gospel,
correct?
As to your questions, re: Rom1 I think it's pretty clear that those who reject God see no value in having Him in their knowledge and this knowledge is a word that essentially means their practical - experiential - knowledge. IOW they see no value having any knowledge of God in their day-to-day life experience Rom1:28.
The interesting things to me about this in the context of all this discussion we've been having on this thread is it seems to clearly leave this choice to have God in their knowledge up to the will and desires and evaluation of men. And the reason they have no excuse for rejecting God is because God has made certain they know of His existence and of certain things about Him.
