Psalms 150:1-6
1 Praise ye the LORD. Praise God in his sanctuary: praise him in the firmament of his power.
2 Praise him for his mighty acts: praise him according to his excellent greatness.
3 Praise him with the sound of the trumpet:a praise him with the psaltery and harp.
4 Praise him with the timbrel and dance:b praise him with stringed instruments and organs.
5 Praise him upon the loud cymbals: praise him upon the high sounding cymbals.
6 Let every thing that hath breath praise the LORD. Praise ye the LORD.
This psalm which concludes the book, and all the Psalter as final doxology, is the most comprehensive, and illuminative illustration of perfect praise in the whole Psalter. In our analysis of it as doxology at the beginning of the book, its essential values are stated. The central place of prayer is the sanctuary, that is, the place of Divine manifestation, whether the earthly temple or the heavenly, matters nothing. The circumference is the firmament of His power which is the outer confine of human consciousness. The reason for praise is that of His mighty acts, whether in creation, redemption, or government. The measure of praise is His excellent greatness, so that it can never end until all the story be exhausted. The method is set forth by a description of the instruments of music constituting a perfect orchestra.
Finally, the one condition of praise is the possession of breath, that is to say, life received from Him must return in praise to Him. The function of life is praise, and the force of praise is life. The note of responsibility and the dignity of choice are alike indicated in the fact that the final psalm is not merely an expression of praise, but a call to its exercise. Thus it is seen that the worship which perfectly glorifies God is not mechanical, but volitional.
