Psalms 119:45

We may observe in these verses, 1. What David experienced of an affection to the law of God: "I seek thy precepts, Psa 119:45. I desire to know and do my duty, and consult thy word accordingly; I do all I can to understand what the will of the Lord is and to discover the intimations of his mind. I seek thy precepts, for I have loved them, Psa 119:47, Psa 119:48. I not only give consent to them as good, but take complacency in them as good for me." All that love God love his government and therefore love all his commandments. 2. What he expected from this. Five things he promises himself here in the strength of God's grace: - (1.) That he should be free and easy in his duty: "I will walk at liberty, freed from that which is evil, not hampered with the fetters of my own corruptions, and free to that which is good, doing it not by constraint, but willingly." The service of sin is perfect slavery; the service of God is perfect liberty. Licentiousness is bondage to the greatest of tyrants; conscientiousness is freedom to the meanest of prisoners, Joh 8:32, Joh 8:36; Luk 1:74, Luk 1:75. (2.) That he should be bold and courageous in his duty: I will speak of thy testimonies also before kings.
