He is the Rock, his work is perfect: for all his ways are judgment: a God of truth and without iniquity, just and right is he.
There are none can behold their own vileness as it is but in the sight of God's glorious holiness. Sin is darkness, and neither sees itself nor anything else; therefore must His light shine to discover this darkness. Among all the aggravations of sin, nothing doth so demonstrate the madness of it as the perfection, goodness, and absolute unspottedness of God. It is this that takes away all pretence of excuse; and therefore it is that Moses, when he would convince this people of their ways and make them inexcusable, he draws the parallel of God's ways and their ways, declares what God is, how absolutely perfect in Himself and in His works, and had given no cause for provocation to them to depart from Him. And then how odious must their departing be! When both are painted on a board before their eyes, it makes sin become exceeding sinful. There are two things in sin that exceedingly abuse the creature, the iniquity of it and folly of it. It is contrary to all equity and reason to depart from Him that hath made us and given us a law, to whom we are by so many obligations tied. But what is the madness of it, to depart from the Fountain of living waters and dig broken cisterns that can hold none! This is a thing that the heavens may be astonished at; and if the earth had the sense to understand such a thing, the whole fabric of it would tremble for horror at such folly of reasonable souls. And this evil hath two evils in it — we forsake life and love death, go from Him and choose vanity. It is great iniquity to depart without an offence on His part. He may appeal to all our consciences, and let them sit down and examine His way most narrowly. "What iniquity have ye found in Me? What cause have ye to leave Me?" But when withal He is a living Fountain, He is our glory, He is a fruitful land, a land of light, our ornament and attire; in a word, our life and our consolation, our happiness and our beauty. What word shall be found to express the extreme madness of men to depart from such an one, and change their glory into that which doth not profit? If either He were not a Fountain of living waters, or if there were any fountain beside that could yield water to satisfy the unsatiable desires of men, it were more excusable; but what shadow shall be found to cover such an iniquity, that is both infinite sin and incomparable loss? Oh, that men would consider how good the blessed Lord is, how He is alone and nothing beside Him in heaven and earth; all broken cisterns, all unprofitable; He only self-sufficient, all others insufficient, and therefore a proportioned good for our necessity and desires; and I am sure you would be constrained to cry out with David, "Whom have I in heaven with Thee, or in earth beside Thee? It is good for me to draw near to God." You would look on drawing near and walking with Him and before Him not only as the most reasonable thing, but the best thing, most beautiful for you, most profitable for you, and all other ways would be looked on as the ways of death.
