Idolatry is the supreme sin and unbelief is the child of idolatry. Both are libels on the character of the Most High and the Most Holy. He that believeth not God hath made him a liar, wrote the apostle John. A God who lies is a God without character, and where there is no character there can be no confidence. This is the moral logic of unbelief. The unbeliever refuses to trust God because his conception of God is base and ignoble. That he does not burn incense to a graven image does not make him less an idolater, unless we want to make a distinction and say that the idolater worships his false god while the unbeliever refuses to do even that. The joyous message of Christianity is that there is a way back from this place of unbelief and alienation. He that cometh to God must believe that he is, and that he is a rewarder of them that diligently seek him. The gospel message declares that the wronged God took the wrong upon Himself in order that the one who committed the wrong might be saved. Repentance is among other things a sincere apology to God for distrusting Him so long, and faith is throwing oneself upon Christ in complete confidence. Thus by faith reconciliation is achieved between God and man.
