The absurdity of the naturalist arriving at a knowledge of God through reason. Or more succinctly, the absurdity of naturalism.

[Lou Newton]

Fantastic Barry. This man shows the irrational reasoning to believe in the naturalist beliefs.

This is similar to the argument made by C. S. Lewis in Mere Christianity.
This guy in the video is funny.
This argument of naturalism is why we must not trust human reason but revelation any more than we ought to depend upon our own righteousness.
His confidence in human reason is because man is created in the image of God and assumes that human reason is part of what the image of God means.
Someone ought to do a Bible study to discover the truth of this idea.
