“Praise the LORD! Blessed is the man who fears the LORD, who greatly delights in his commandments! His offspring will be mighty in the land; the generation of the upright will be blessed. Wealth and riches are in his house, and his righteousness endures forever. Light dawns in the darkness for the upright; he is gracious, merciful, and righteous.”
The 112th psalm is a psalm of comfort in which the pious, who fear God, are praised for their good life and are promised eternal comfort against all trouble. They are especially commended to a sincere confidence and trust in God’s grace, so that they may be undismayed and undaunted (which is real, true faith) until they see the destruction of the godless and their foes.
O Lord, the Reward of them that fear You, and the Defense of Your people, who in Your Son, Jesus Christ, has promised grace and everlasting righteousness to them that believe, establish our hearts by Your grace that, rooted in the faith of Your Word, we may be able to stand in the day of trial. Strengthen us to resist the enticing lust of sin, and to triumph over Satan, death, and hell through Jesus Christ. Amen.
