Exodus 34:5-8 The LORD descended in the cloud and stood with him there, and proclaimed the name of the LORD. The LORD passed before him and proclaimed, “The LORD, the LORD, a God merciful and gracious, slow to anger, and abounding in steadfast love and faithfulness, keeping steadfast love for thousands, forgiving iniquity and transgression and sin, but who will by no means clear the guilty, visiting the iniquity of the fathers on the children and the children’s children, to the third and the fourth generation.” And Moses quickly bowed his head toward the earth and worshiped.
The Lord descended by some open token of his presence and manifestation of his glory in a cloud, and thence proclaimed his NAME; that is, the perfections and character which are denoted by the name JEHOVAH. The Lord God is merciful; ready to forgive the sinner, and to relieve the needy. Gracious; kind, and ready to bestow undeserved benefits. Long-suffering; slow to anger, giving time for repentance, only punishing when it is needful. He is abundant in goodness and truth; even sinners receive the riches of his bounty abundantly, though they abuse them. All he reveals is infallible truth, all he promises is in faithfulness. Keeping mercy for thousands; he continually shows mercy to sinners, and has treasures, which cannot be exhausted, to the end of time. Forgiving iniquity, and transgression, and sin; his mercy and goodness reach to the full and free forgiveness of sin. And will by no means clear the guilty; the holiness and justice of God are part of his goodness and love towards all his creatures. In Christ’s sufferings, the Divine holiness and justice are fully shown, and the evil of sin is made known. God’s forgiving mercy is always attended by his converting, sanctifying grace. None are pardoned but those who repent and forsake the allowed practice of every sin; nor shall any escape, who abuse, neglect, or despise this great salvation. Moses bowed down, and worshipped reverently. Every perfection in the name of God, the believer may plead with Him for the forgiveness of his sins, the making holy of his heart, and the enlargement of the Redeemer’s kingdom. (Henry)
All sin of every sort is deviation from a standard to which we ought to be conformed. There is a path which is ‘right’ and one which is ‘wrong,’ whether we believe so or not. There are hedges and limitations for us all. This law extends to the ordering of all things, whether great or small. If a line be absolutely straight, and we are running another parallel to it, the smallest possible wavering is fatal to our copy. And the smallest deflection, if produced, will run out into an ever-widening distance from the straight line. Every sin is apostasy from or rebellion against God. Our obligations are not merely to a law, but to Him who enacted it. So it becomes plain that the very centre of all sin is the shaking off of obedience to God. Living to ‘self’ is the inmost essence of every act of evil, and may be as virulently active in the smallest trifle as in the most awful crime. How infinitely deeper and darker this makes sin to be! When one thinks of our obligations and of our dependence, of God’s love and care, what an ‘evil and a bitter thing’ every sin becomes! Every sin misses the goal at which we should aim. By it we fall short of the loftiest purpose. Whatever we gain we lose more. For consider what human life might be: full of God and full of joy. Consider what the ‘fruits’ of sin are. ‘Apples of Sodom.’ How sin leads to sorrow. This is an inevitable law. Sin fails to secure what it sought for.
In it all things work under God, but only for ‘good’ to them who love God. To all others, sooner or later, the Nemesis comes. ‘Ye shall eat of the fruit of your doings.’ God forgives, and therefore He does not leave sin unpunished. It is divine mercy that strikes. The end of His chastisement is to separate us from our sins. Divine forgiveness and retributive justice both centre in the revelation of the Cross. (MacLaren)
