Scripture gives us insight:
1) Pride keeps one from seeking God. Any admittance of guilt is a blow to the pride of the human heart;
“For the wicked boasts of his heart's desire, and the greedy man curses and spurns the LORD. The wicked, in the haughtiness of his countenance, does not seek Him. All his thoughts are, ‘There is no God.’ His ways prosper at all times; Your judgments are on high, out of his sight; as for all his adversaries, he snorts at them. He says to himself, ‘I will not be moved; throughout all generations I will not be in adversity.’ . . . He says to himself, ‘God has forgotten; He has hidden His face; He will never see it.’ . . . Why has the wicked spurned God? He has said to himself, ‘You will not require it.’” (Psalm 10:3-6,11,13).
