Let my soul live that it may praise You, And let Your ordinances help me.
NASB95
Let my soul live and praise you, and let your rules help me.
ESV
Let my soul live, and it shall praise thee; and let thy judgments help me.
KJV

There must be life, in order to praise. For how can the dead speak? Yet is it as natural for the living soul to praise, as for the living man to speak. And is not the life that the Psalmist is now praying for, the salvation for which he was longing? The taste that he has received makes him hunger for a higher and continued enjoyment; not for any selfish gratification, but that he might employ himself in the praise of His God. Indeed, the close of this Psalm exhibits that pervading character of praise which has been generally remarked in the concluding Psalms of this sacred book. Yet he alone is fitted for this heavenly exercise, of whom it has been said, "This my son was dead, and is alive again." And how will he, who has "looked to the hole of the pit whence he was dug," who has been awakened to a sight of that tremendous gulf, from which he is but "scarcely saved," long to give utterance to the effusions of a praising heart! How will he cry for the quickening influence of "the Lord and Giver of life," to stir him up to this delightful privilege! Praise springs from prayer—Let my soul live, and it shall praise You. When the breathing of life into our souls enlivens our services, we become, in the noblest sense, "living souls."

Too often, however, the consciousness of inconsistency, carelessness, and unspirituality, damps our song. But let every recollection of our sin be accompanied with an humble yet assured confidence in the Lord's pardoning grace. The abominations of a desperately wicked and unsearchably deceitful heart may well lead us to "abhor ourselves in dust and ashes." Yet in the lowest depths of abasement, the Savior's blood, applied to the conscience, "cleanses from all sin." He who once "passed by us, and saw us polluted in our blood, and said unto us, when we were in our blood, Live"—still "holds our souls in life;" covering our daily infirmities, and maintaining our everlasting acceptance before God.

But while the song of praise dwells on our lips for life thus freely given, let us guard against all hindrance to its growth and influence. For if the life within waxes low, praise will be dull and heartless. But when the assured believer cries with acceptance—Let my soul live, and it shall praise You—see how his spirit kindles with holy fire, "Blessed be the God and Father of our Lord Jesus Christ, which according to His abundant mercy has begotten us again unto a lively hope by the resurrection of Jesus Christ from the dead!" The work of praise is now his nature, his element, his delight. No wonder, then, that he continues his cry for the daily renewal of his spiritual life, that he may return to this sweet foretaste of heaven—Let my soul live. And, indeed, this life—the more it is known, the more will it form the constant matter for prayer. For what besides makes existence tolerable to a child of God? The mere actings of a sickly pulsation can never satisfy him. Considering how much nearer he might live to God than he has yet known, he longs for more vigorous influence of the Divine principle. In his most active enjoyments, his insufficiency for this sacred work presses upon him, and stirs up petition for help—Let Your judgments help me. Give me such an enlightened apprehension of Your word, of Your character, and of Your perfections as the God of my salvation, as may furnish abundant matter of unceasing praise; so that my daily exercise may be, "Giving thanks always for all things unto God and the Father, in the name of our Lord Jesus Christ."

"Let my soul live." Fill it full of life, preserve it from wandering into the ways of death, give it to enjoy the indwelling of the Holy Spirit, let it live to the fullness of life, to the utmost possibilities of its new-created being.

"And it shall praise you." It shall praise you for life, for new life, for eternal life, for you are the Lord and Giver of life. The more it shall live, the more it shall praise, and when it shall live in perfection it shall praise you in perfection. Spiritual life is prayer and praise.

"And let your judgments help me." While I read the record of what you have done, in terror or in love, let me be quickened and developed. While I see your hand actually at work upon me, and upon others, chastening sin, and smiling upon righteousness, let me be helped both to live aright and to praise you aright Let all your deeds in providence instruct me, and aid me in the struggle to overcome sin and to practice holiness. This is the second time he has asked for help in this portion; he was always in need of it, and so are we.
