Fourthly, Consider the person against whom sin is committed
This is whom it highly offends and provokes: it is God (Ps 51:4). To Him you owe yourself and all that you have. It is He who made and preserves you (Acts 17:26-28). Yet, though you have sinned, God does not desire your death (Ezek 33:11; 18:32); nor does He afflict you willingly (Lam 3:33). Rather, He desires that you should humble yourself, repent, and live, so that you might be saved. God gave His only begotten Son to death to ransom sinners like you (John 3:16). He uses His ministers to make known His word and good-will towards you, making proclamation, that if you will repent and believe, you shall be saved. Indeed, He entreats you, by His ministers, to be reconciled to him (2 Cor 5:20).
Your only hope that you may yet live must be in God, who is rich in goodness, forbearance, and long-suffering (2 Pet 3:9). If you despise His goodness and continue in your sin, provoking the eyes of his glory (Isa 3:8), He shall be a terrible and revengeful God to you (Nah 1:2). If you still err in heart and refuse to walk in His ways, He has sworn, in His wrath, that you shall not enter into His rest (Heb 3:11). His wrath is a consuming fire (Heb 12:29); He is ready and able to destroy body and soul in the eternal vengeance of hell-fire (Matt 10:28).
Fifthly, Consider sin’s evil effects
Sin brought a curse upon the whole creation (Gen 3:17; Rom 8:20). From man’s sin, the creatures [i.e., the rest of creation] are defective, and oftentimes unserviceable, even hurtful, to you. From your sins come all manner of diseases and afflictions that ever befell you. Your sin (until it be repented of and pardoned) makes you hateful to God (Ps 11:5); it separates you and God (Isa 59:2), causing Him to withhold good things from you (Jer 5:25), and inflicts evil upon you, even in this life. It defiles the whole man (Titus 1:15), and every renewed act of sin strengthens the “body of sin”, and works a decay of grace in you, even though you be regenerate. And if your sin involves gross iniquity, though it might not numb and sear your conscience, yet (if your conscience is tender) it will wound it and break its peace. Your conscience will trouble you as specks in your eye, or thorns over your feet (Ps 51). Sin will cause terrors and doubts of your salvation from God withdrawing His favour and loving countenance from you. And, if you are not in Christ, it will, in the end, bring everlasting damnation upon you (Matt 25:46 & Rev 21:8).
