1. How they denied the power of godliness, and wholly cast that off (v. 12): I have written to him the great things of my law; this intimates the privilege they enjoyed, as having God's statutes and judgments made known to them, and being entrusted with the lively oracles. Note, (1.) The things of God's law are magnalia Dei—the great things of God. They are things that proclaim the greatness of the Law-maker, and things of great use and great importance to us; they are our life, and our eternal welfare depends upon our observance of them and obedience to them; they will make us great if we make a right use of them; and they are things which God will magnify and make honourable. (2.) It is a great privilege to have the things of God's law written; thus they are reduced to a greater certainty, spread the further, and last the longer, with much less danger of being embezzled and corrupted than if they were transmitted by word of mouth only. (3.) The things of God's law are of his own writing; for Moses and the prophets were his amanuenses, and holy men wrote as they were moved by the Holy Ghost. (4.) It is the advantage of those that are members of the visible church that these great things are written to them, are intended for their direction, and so they must receive them; what things were written in former ages were written for our learning, and are profitable for us. And, if those were happy who had the great things of God's law written to them, how much happier are we who have the gospel written to us! But see how this privilege was slighted; these great things of the law were counted as a strange thing, as unintelligible and unreasonable (which might therefore be slighted, because not to be fathomed, not to be accounted for), or as foreign, and things of no concernment to them, things that they had nothing to do with nor were to be governed by; they used those things as strangers, which they were shy of, and knew not how to bid welcome. We desire not the knowledge of thy ways. Note, [1.] God having written to us the great things of his law, we ought to make them familiar to us, as our nearest relations (Prov. vii. 3, 4); for therefore we have them written, that they may talk with us, Prov. vi. 22. [2.] We make nothing of the things of God's law if we make strange of them, as if they did not affect us and therefore we need not be affected with them.
