I said it earlier, but I think this answers all the atheism stuff perfectly: (the bold is my emphasis only)
Romans 1: 18:20
[SUP]
18 [/SUP]For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who by their unrighteousness
suppress the truth. [SUP]
19 [/SUP]For what can be known about God is plain to them, because God has shown it to them. [SUP]
20 [/SUP]For his invisible attributes, namely, his eternal power and divine nature,
have been clearly perceived, ever since the creation of the world,[SUP]
[a][/SUP] in the things that have been made. So they are without excuse.
Atheists know there is a God. They choose to verbalize disbelief for their own reasons. I think Shiloah is just basically agreeing with that idea. That there is no use arguing with someone who chooses to believe something else.
