Matthew Henry on Psalms 103:19-22

He who made all, rules all, and both by a word of power. He disposes all persons and things to his own glory. There is a world of holy angels who are ever praising him. Let all his works praise him. Such would have been our constant delight, if we had not been fallen creatures. Such it will in a measure become, if we are born of God. Such it will be for ever in heaven; nor can we be perfectly happy till we can take unwearied pleasure in perfect obedience to the will of our God. And let the feeling of each redeemed heart be, Bless the Lord, O my soul.
