Charles H. Spurgeon on Psalms 119:68

Thou art good, and doest good. There is a good God set before us, that we may not take tip with any low pattern of goodness. He is represented to us as all goodness. He is good in his nature; and his work is agreeable to his nature; nothing is wanting to it, or defective in it. Nothing can be added to it to make it better. Philo saith, w ontwl wn to prwtoon agayov: the first being must needs be the first good. As soon as we conceive that there is a God, we presently conceive that he is good, He is good of himself, good in himself, goodness itself, and both the fountain and the pattern of all the good that is in the creatures.

1. As to his nature, he is originally "good", good in himself, and good to others; as the sun hath light in himself, and giveth light to all other things. Essentially good; not only good, but goodness itself. Goodness in us is an accessory quality or superadded gift; but in God it is not a quality, but his essence. In a vessel that is gilded with gold the gilding or lustre is a superadded quality; but in a vessel all of gold, the lustre and the substance is the same. God is infinitely good; the creatures' good is limited, but there is nothing to limit the perfection of God, or give it any measure. He is an ocean of goodness without banks or bottom. Alas! what is our drop to this ocean! God is immutably good; his goodness can never be more or less than it is; as there can be no addition to it, so no subtraction from it. Man in his innocency was 'peccabilis', or liable to sin, afterwards 'peccator',or an actual sinner; but God ever was and is good. Now this is the pattern propounded to us, but his nature is a great deep. Therefore

2. As to his work; "he doeth good." What hath God been acting upon the great theatre of the world but goodness for these six thousand years? Acts 14:17, "Nevertheless he left not himself without witness, in that he did good, and gave us rain from heaven, and fruitful seasons, filling our hearts with food and gladness." He left not himself without a witness, anayopiwn, not by taking vengeance of their idolatries, but by distributing benefits. This is propounded to our imitation, that our whole life may be nothing else but doing good: Matthew 5:48, "Be ye therefore perfect, even as your Father which is in heaven is perfect." Well, therefore, doth the Psalmist say, "Teach me thy statutes." Thomas Manton.
