Psalms 32:1

This psalm is entitled Maschil, which some take to be only the name of the tune to which it was set and was to be sung. But others think it is significant; our margin reads it, A psalm of David giving instruction, and there is nothing in which we have more need of instruction than in the nature of true blessedness, wherein it consists and the way that leads to it - what we must do that we may be happy. There are several things in which these verses instruct us. In general, we are here taught that our happiness consists in the favour of God, and not in the wealth of this world - in spiritual blessings, and not the good things of this world. When David says (Psa 1:1), Blessed is the man that walks not in the counsel of the ungodly, and (Psa 119:1), Blessed are the undefiled in the way, the meaning is, "This is the character of the blessed man; and he that has not this character cannot expect to be happy:" but when it is here said, Blessed is the man whose iniquity is forgiven, the meaning is, "This is the ground of his blessedness: this is that fundamental privilege from which all the other ingredients of his blessedness flow." In particular, we are here instructed, I. Concerning the nature of the pardon of sin.
