Psalms 18:30

30.The way of God is perfect. The phrase, The way of God, is not here taken for his revealed will, but for his method of dealing towards his people. The meaning, therefore, is, that God never disappoints or deceives his servants, nor forsakes them in the time of need, (as may be the case with men who do not aid their dependants, except in so far as it contributes to their own particular advantage,) but faithfully defends and maintains those whom he has once taken under his protection. But we will never have any nearness to God, unless he first come near to us by his word; and, for this reason, David, after having asserted that God aids his people in good earnest, adds, at the same time, that his word is purified. Let us, therefore, rest assured that God will actually show himself upright towards us, seeing he has promised to be the guardian and protector of our welfare, and his promise is certain and infallible truth. That by the word we are not here to understand the commandments, but the promises of God, is easily gathered from the following clause, where it is said, He is a shield to all those who trust in him It seems, indeed, a common commendation to say, that the word of God is pure, and without any mixture of fraud and deceit, like silver which is well refined and purified from all its dross. But our unbelief is the cause why God, so to speak, is constrained to use such a similitude, for the purpose of commending and leading us to form exalted conceptions of the steadfastness and certainty of his promises; for whenever the issue does not answer our expectation, there is nothing to which we are naturally more prone than forthwith to begin to entertain unhallowed and distrustful thoughts of the word of God. For a farther explanation of these words, we would refer our readers to our remarks on Psalms 12:6.
