Here, I. David looks back with comfort upon the respect he had paid to the word of God. He had the testimony of his conscience for him, 1. That he had edified others with what he had been taught out of the word of God (Ps. 119:13): With my lips have I declared all the judgments of thy mouth. This he did, not only as a king in making orders, and giving judgment, according to the word of God, nor only as a prophet by his psalms, but in his common discourse. Thus he showed how full he was of the word of God, and what a holy delight he took in his acquaintance with it; for it is out of the abundance of the heart that the mouth speaks. Thus he did good with his knowledge; he did not hide God’s word from others, but hid it for them; and, out of that good treasure in his heart, brought forth good things, as the householder out of his store things new and old. Those whose hearts are fed with the bread of life should with their lips feed many. He had prayed (Ps. 119:12) that God would teach him; and here he pleads, “Lord, I have endeavoured to make a good use of the knowledge thou hast given me, therefore increase it;” for to him that has shall be given. 2. That he had entertained himself with it: “Lord, teach me thy statutes; for I desire no greater pleasure than to know and do them (Ps. 119:14): I have rejoiced in the way of thy commandments, in a constant even course of obedience to thee; not only in the speculations and histories of thy word, but in the precepts of it, and in that path of serious godliness which they chalk out to me. I have rejoiced in this as much as in all riches, as much as ever any worldling rejoiced in the increase of his wealth. In the way of God’s commandments I can truly say, Soul, take thy ease;” in true religion there is all riches, the unsearchable riches of Christ.
II. He looks forward with a holy resolution never to cool in his affection to the word of God; what he does that he will do, 2 Cor. 11:12. Those that have found pleasure in the ways of God are likely to proceed and persevere in them. 1. He will dwell much upon them in his thoughts (Ps. 119:15): I will meditate in thy precepts. He not only discoursed of them to others (many do that only to show their knowledge and authority), but he communed with his own heart about them, and took pains to digest in his own thoughts what he had declared, or had to declare, to others. Note, God’s words ought to be very much the subject of our thoughts. 2. He will have them always in his eye: I will have respect unto thy ways, as the traveller has to his road, which he is in care not to miss and always aims and endeavours to hit. We do not meditate on God’s precepts to good purpose unless we have respect to them as our rule and our good thoughts produce good works and good intentions in them. 3. He will take a constant pleasure in communion with God and obedience to him. It is not for a season that he rejoices in this light, but “I will still, I will for ever, delight myself in thy statutes, not only think of them, but do them with delight,” Ps. 119:16. David took more delight in God’s statutes than in the pleasures of his court or the honours of his camp, more than in his sword or in his harp. When the law is written in the heart duty becomes a delight. 4. He will never forget what he has learned of the things of God: “I will not forget thy word, not only I will not quite forget it, but I will be mindful of it when I have occasion to use it.” Those that meditate in God’s word, and delight in it, are in no great danger of forgetting it.
