Psalms 103:7

"He made His ways known unto Moses" [Psalm 103:7]. ...For the Law was given with this view, that the sick might be convinced of his infirmity, and pray for the physician. This is the hidden way of God. Thou hadst long ago heard, "Who healeth all thine infirmities." Their infirmities were as yet hidden in the sick; the five books were given to Moses: the pool was surrounded by five porches; he brought forth the sick, that they might lie there, that they might be made known, not that they might be healed. The five porches discovered, but healed not, the sick; the pool healed when one descended, and this when it was disturbed: [John 5:2-4] the disturbance of the pool was in our Lord's Passion. ...Since therefore this is a mystery there, he teacheth that the Law was given that sinners might be convinced of their sin, and call upon the Physician in order to receive grace. ...Therefore, as I had begun to say, because this is a great mystery in the Law, that it was given with this view, that by the increase of sin, the proud might be humbled, the humbled might confess, the confessing might be healed; these are the hidden ways, which He made known to Moses, through whom He gave the Law, by which sin should abound, that grace might more abound. ..."He hath made known His good pleasure unto the children of Israel." To all the children of Israel? To the true children of Israel; yea, to all the children of Israel. For the treacherous, the insidious, the hypocrites, are not children of Israel. And who are the children of Israel? "Behold an Israelite indeed, in whom is no guile." [John 1:47]

...and that we received this law in our very nature, and that our Creator entrusted to us the impartial rule of conscience, these I say, are proofs of the greatest grace and unspeakable lovingkindness. And the recovery of this law after it had become corrupt, by means of the written (Law), this too was the work of grace. For what might have been expected to follow was, that they who falsified the law once given should suffer correction and punishments; but what actually took place was not this, but, on the contrary, an amending of our nature, and pardon, not of debt, but given through mercy and grace. For to show that it was of grace and mercy, hear what David saith; "The Lord executeth righteousness and judgment for all that are oppressed; He made known His ways unto Moses, His acts unto the children of Israel": and again; "Good and upright is the Lord, therefore will He give laws to them that are in the way."

Or by his ways we may understand his precepts, the way which he requires us to walk in; and by his acts, or designs (as the word signifies), his promises and purposes as to what he will do with us.

He made known his ways unto Moses,....

He made known his ways unto Moses. Moses was made to see the manner in which the Lord deals with men; he saw this at each of the three periods of his life, in the court, in retirement, and at the head of the tribes of Israel. To him the Lord gave specially clear manifestations of his dispensations and modes of ruling among mankind, granting to him to see more of God than had before been seen by mortal man, while he cornmaned with him upon the mount. His acts unto the children of Israel. They saw less than Moses, for they beheld the deeds of God without understanding his method therein, yet this was much, very much, and might have been more if they had not been so perverse; the stint was not in the revelation, but in the hardness of their hearts. It is a great act of sovereign grace and condescending love when the Lord reveals himself to any people, and they ought to appreciate the distinguished favour shown to them. We, as believers in Jesus, know the Lord's ways of covenant grace, and we have by experience been made to see his acts of mercy towards us; how heartily ought we to praise our divine teacher, the Holy Spirit, who has made these things known to us, for had it not been for him we should have continued in darkness unto this day, "Lord, how is it that thou wilt manifest thyself unto us and not unto the world?" Why hast thou made us "of the election who have obtained it" while the rest are blinded? Observe how prominent is the personality of God in all this gracious teaching— "He made known." He did not leave Moses to discover truth for himself, but became his instructor. What should we ever know if he did not make it known? God alone can reveal himself. If Moses needed the Lord to make him know, how much more do we who are so much inferior to the great law-giver?
