Psalms 106:3

3Blessed are they that keep judgment I make a distinction between this and the preceding verse, and yet so as to preserve the connection between them. For the prophet, having declared the magnitude of God’s power to be such that no tongue could utter all its praises, now says, that the praises of the lip merely are not acceptable to God, but that the concurrence of the heart is indispensable, nay, that even the whole of our deportment must be in unison with this exercise. Now, when he first commands to keep judgment, and then to work righteousness, he gives us a short description of genuine godliness. I have no doubt, that in the former clause he describes the sincere affection of the heart, and that, in the latter, he refers to external works. For we know, there is nothing but the mere shadow of righteousness, unless a man cordially devote himself to the practice of honesty. He requires perseverance, too, that no one may imagine that he has discharged this duty properly, excepting he whose constant and continued aim it is to live righteously and justly. We behold not a few who have only an empty profession; others show some signs of virtue, but do not maintain a consistent course of conduct.
