Sin is the great spoiler of all God's works. Sin turned an archangel into an arch-fiend, and angels of light into spirits of evil. Sin looked on Eden and withered all its flowers. Ere sin had come the Creator said of the new-made earth, "It is very good"; but when sin had entered, it grieved God at his very heart that he had made such a creature as man. Nothing tarnishes beauty so much as sin, for it mars God's image and erases his superscription.
Moreover, sin makes God's creatures unhappy, and shall not the Lord, therefore, abhor it? God never designed that any creature of his hand should be miserable. He made the creatures on purpose that they should be glad; he gave the birds their song, the flowers their perfume, the air its balm; he gave to day the smiling sun and to night its coronet of stars; for he intended that smiles should be his perpetual worship, and joy the incense of his praise. But sin has made God's favourite creature a wretch, and brought down God's offspring, made in his own image, to become naked, and poor, and miserable; and therefore God hateth sin, and is pressed down under it, because it maketh the objects of his love unhappy at their heart.
Moreover, remember that sin attacks God in all his attributes, assails him on his throne, and stabs at his existence. What is sin? Is it not an insult to God's wisdom? O sinner, God biddeth thee do his will; when thou doest the contrary it is because thou dost as much as say, "I know what is good for me, and God does not know." You do in effect declare that infinite wisdom is in error, and that you, the creature of a day, are the best judge of happiness. Sin impugns God's goodness; for by sin you declare that God has denied you that which would make you happy, and this is not the part of a good, tender, and loving Father. Sin cuts at the Lord's wisdom with one hand, and at his goodness with the other.
Sin also abuses the mercy of God. When you, as many of you have done, sin with the higher hand because of his longsuffering towards you; when, because you have no sickness, no losses, no crosses, therefore you spend your time in revelry and obstinate rebellhief? It is no small grief to the loving father to see his substance spent with harlots in riotous living; he cannot endure it that his child should be so degraded as to turn even the mercy which would woo him to repentance into a reason why he should sin the more against him. Besides, let me remind the careless and impenitent that every sin is a defiance of divine power. In effect it is lifting your puny fists against the majesty of heaven, and defying God to destroy you. Every time you sin, you defy the Lord to prove whether he can maintain his law or no. Is this a slight thing, that a worm, the creature of a day, should defy the Lord of ages, the God that filleth and upholdeth all things by the word of his power? Well may he be weary, when he has to bear with such provocations and insults as these! Mention what attribute you will, and sin has blotted it; speak of God in any relationship you choose, and sin has cast a slur upon him. It is evil, only evil, and that continually: in every view of it it must be offensive to the Most High. Sinner, dost thou know that every act of disobedience to God's law is virtually an act of high treason? What dost thou do but seek to be God thyself, thine own master, thine own lord? Every time thou swervest from his will, it is to put thy will into his place; it is to make thyself a god, and to undeify the Most High. And is this a little offence, to snatch from his brow the crown, and from his hand the sceptre? I tell thee it is such an act that heaven itself could not stand unless it were resented: if this crime were suffered to go unpunished, the wheels of heaven's commonwealth would be taken from their axles, and the whole frame of moral government would be unhinged. Such a treason against God shall certainly be visited with punishment.
To crown all, sin is an onslaught upon God himself, for sin is atheism of heart. Let his religious profession be what it may, the sinner hath said in his heart, "No God." Ruler. Is this a trifle? To be a Deicide! To desire to put God out of his own world! Is this a thing to be winked at? Can the Most High hear it and not be pressed down beneath its weight? I pray you do not think that I would make a needless outcry against sin and disobedience. It is not in the power of human imagination to exaggerate the evil of sin, nor will it ever be possible for mortal lips, though they should be touched like those of Esaias with a live coal from off the altar, to thunder out the ten-thousandth part of the enormity of the least sin against God. Think, dear friends! We are his creatures, and yet we will not do his will. We are fed by him, the breath in our nostrils he gives us, and yet we spend that breath in murmuring and rebellion.
Once more, we are always in the sight of our omniscient God, and yet the presence of God is not enough to compel us to obedience. Surely if a man should insult law in the very presence of the lawgiver, that were not to be borne with; but this is your case and mine. We must confess, "Against thee, thee only, have I sinned, and done this evil in thy sight." We must remember also, that we offend, knowing that we are offending. We do not sin as the Hottentot, or the cannibal. We in England sin against extraordinary light and sevenfold knowledge; and is this a light thing? Can you expect that God shall pass by wilful and deliberate offences? Oh, that these lips had language, that this heart could burn for once! for if I could declare the horrible infamy of sin it would make the blood chill in even a haughty Pharaoh's veins, and proud Nebuchadnezzar would bow his head in fear. It is indeed a terrible thing to have rebelled against the Most High. The Lord have mercy upon his servants and forgive them.
This is our first point, but I cannot teach you it, God himself must teach it by his Spirit. Oh, that the Holy Ghost may make you feel that sin is exceedingly sinful, so that it is grievous and burdensome to God!
