Psalms 104:33

33. I will sing to Jehovah whilst I live Here the Psalmist points out to others their duty by his own example, declaring, that throughout the whole course of his life he will proclaim the praises of God without ever growing weary of that exercise. The only boundary which he fixes to the celebration of God’s praises is death; not that the saints, when they pass from this world into another state of existence, desist from this religious duty, but because the end for which we are created is, that the divine name may be celebrated by us on the earth. Conscious of his unworthiness to offer to God so precious a sacrifice, he humbly prays, (verse 34,) that the praises which he will sing to God may be acceptable to him, although they proceed from polluted lips. It is true, that there is nothing more acceptable to God, nor any thing of which he more approves, than the publication of his praises, even as there is no service which he more peculiarly requires us to perform. But as our uncleanness defiles that which in its own nature is most holy, the prophet with good reason betakes himself to the goodness of God, and on this ground alone pleads that He would accept of his song of praise. Accordingly, the Apostle, in Hebrews 13:15 teaches that our sacrifices of thanksgiving are well pleasing to God, when they are offered to him through Christ. It being however the case, that whilst all men indiscriminately enjoy the benefits of God, there are yet very few who look to the author of them, the prophet subjoins the clause, I will rejoice in the Lord; intimating, that this is a rare virtue; for nothing is more difficult than to call home the mind from those wild and erratic joys, which disperse themselves through heaven and earth in which they evanish, that it may keep itself fixed on God alone.
