Matthew Henry on Psalms 106:1-5

None of our sins or sufferings should prevent our ascribing glory and praise to the Lord. The more unworthy we are, the more is his kindness to be admired. And those who depend on the Redeemer's righteousness will endeavour to copy his example, and by word and deed to show forth his praise. God's people have reason to be cheerful people; and need not envy the children of men their pleasure or pride.
