If thou sinnest, what dost thou against him?.... Sin is expressly said to be against God, Ps 51:4; it is contrary to his nature, as any opposites can be to each other: it is against his law, a breach and violation of it; and so against his supreme legislative power and authority, and a contempt of it; it is what he is angry with and is provoked by, being what he hates and abhors, and is abominable in his sight.
But then he cannot be supposed to be so affected with it to be ruffled and discomposed, or his peace be disturbed, and his happiness in the least broke in upon; for affections are only attributed to him after the manner of men; much less is he so affected hereby as to be hurt or in danger of being destroyed, nor even of being dethroned: men can no more reach him by any hostile action of theirs, such as sin is, than they can reach the sun and stop its course, lessen its light or pluck it from its orbit.
Or, "what canst thou work for him?" as Mr. Broughton; by way of atonement or satisfaction for sin?
