The dilemma of the prosperity of the wicked, is such a dilemma that it caused the psalmist pain (vs. 16). He couldn’t explain it to the generation of the Lord’s children (vs. 15). It is such a dilemma because the Torah promises blessings for the obedient and curses for the disobedient (Deu 28). But the psalmist rightly observes that it is the wicked who seem to inherit every blessing, and the righteous who are plagued and chastened every morning.
But the end of the wicked is destruction, while the end of the righteous is glory. In the mean time, let us draw near to God for our good, and put our trust in the Lord our God! The just shall live by faith!
