What you have here articulated is an example of the common saying, "There are no atheists in foxholes."

It is also an example of the presuppositionalist assertion that all men know deep down that there is a God on whom they depend and to whom they must give an account, but they willfully suppress this truth due to their desire for autonomy to pursue sinful passions.

Or, as it is stated in Scripture: "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."
