Ps 102:7

“"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]”
