The excuse that is banished, the excuse every pagan hopes in vain to use, the excuse that is exploded by God’s self-revelation in nature is the pretended, vacuous, dishonest appeal to ignorance. No one will be able to approach the judgment seat of God justly pleading, “If only I had known You existed, I would surely have served You.” That excuse is annihilated. No one can lightly claim “insufficient” evidence for not believing in God.
