“Imagine a person who comes in here tonight and argues ‘no air exists’ but continues to breathe air while he argues. Now intellectually, atheists continue
to breathe—they continue to use reason and draw scientific conclusions [which assumes an orderly universe], to make moral judgments [which assumes absolute values]—but the atheistic view of things would in theory make such ‘breathing’ impossible. They are breathing God’s air all the time they are arguing against Him.”
Greg Bahnsen
For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men, who by their unrighteousness suppress the truth. For what can be known about God is plain to them, because God has shown it to them. For His invisible attributes, namely, His eternal power and divine nature, have been clearly perceived, ever since the creation of the world, in the things that have been made. So they are without excuse.
(Romans 1:18-20 ESV)
