One must understand God exists. “Know ye that the LORD he is God: it is he that hath made us, and not we ourselves; we are his people, and the sheep of his pasture” (Psalm 100:3). There is “One God and Father of all, who is above all, and through all, and in you all” (Ephesians 4:6). “Thine, O LORD, is the greatness, and the power, and the glory, and the victory, and the majesty: for all that is in the heaven and in the earth is thine; thine is the kingdom, O LORD, and thou art exalted as head above all” (1 Chronicles 29:11). “O the depth of the riches both of the wisdom and knowledge of God! how unsearchable are his judgments, and his ways past finding out! … For of him, and through him, and to him, are all things: to whom be glory for ever” (Romans 11:33,36). “For the LORD is a great God” (Psalm 95:3).
One must understand sin is a violation of God’s Will. “Whosoever committeth sin transgresseth also the law: for sin is the transgression of the law” (1 John 3:4). “…For where no law is, there is no transgression” (Romans 4:15; cf. 5:13). “All unrighteousness is sin…” (1 John 5:17).
One must understand sin separates one from God. No one is exempt from sin. “There is none righteous, no, not one. … For all have sinned and come short of the glory of God” (Romans 3:23,10). “The LORD’S hand is not shortened, that it cannot save; neither his ear heavy, that it cannot hear: But your iniquities have separated between you and your God, and your sins have hid his face from you, that he will not hear” (Isaiah 59:1-2). Before becoming a child of God, one is “…dead in trespasses and sin” (Ephesians 2:1). Sin defiles a person (Mark 7:20-23). When one turns from what is right and commits that which is wrong, he will pay for his evil, if not in this life, in the judgment to come (Ezekiel 18:26-30).
God desires that all men everywhere turn from their evil so they will not have to suffer for it. “…Repent, and turn yourselves from all your transgressions; so iniquity shall not be your ruin. Cast away from you all your transgressions, whereby ye have transgressed; and make you a new heart and a new spirit: for why will ye die? …For I have no pleasure in the death of him that dieth, …wherefore turn yourselves, and live ye” (Ezekiel 18:30-32).
