“O how love I Thy Law I it is my meditation all the day.”
“O how love I Thy Law!” It is a note of exclamation. He loves so much that he must express his love, and express it to God in rapturous devotion. In making the attempt he perceives that his emotion is inexpressible, and therefore he cries, “O how I love!” We not only reverence but love the Law, we obey it out of love, and even when it chides us for disobedience we love it none the less. The law is God’s Law, and therefore it is our love. We love it for its holiness, and pine to be holly; we love it for its wisdom, and study to be wise; we love it for its perfection, and long to be perfect. Those who know the power of the gospel perceive an infinite loveliness in the Law as they see it fulfilled and embodied in Christ Jesus.
“It is my meditation all the day” This was both the effect of his love to the law and the cause of that love. He meditated in God’s word because he loved it, and loved it the more because he meditated in it. He could not have enough of it, so ardently did he love it; all the day was not too long for his converse with it. His morning prayer, his noonday thought, his evensong were all out of Holy Writ; yea, in his worldly business he still kept his mind saturated with the Law of the Lord. It is said of some men that the more you know them the less you admire them; but the reverse is true of God’s word. Familiarity with the word of God breeds affection, and affection seeks yet greater familiarity.
When “Thy law” and “my meditation” are together all the day, the day grows holy, devout, and happy, and the heart lives with God in love to His Word, and delight therein. David turned away from all else but the word and will of the Lord, for in the preceding verse he tells us that he had seen an end of all perfection; but he turned in unto the law and tarried there the whole day of his life on earth, growing henceforth wiser and holier.
