“Praise ye the LORD. Praise the LORD, O my soul. While I live will I praise the LORD: I will sing praises unto my God while I have any being” (Psalm 146:1,2).
Why does the Psalmist exhort, “Praise the LORD?”
Let us continue reading: “ Put not your trust in princes, nor in the son of man, in whom there is no help.  His breath goeth forth, he returneth to his earth; in that very day his thoughts perish.” Our fellow man, no matter how “dedicated” or “promising,” will eventually fail and dissatisfy us.
The LORD God, JEHOVAH God, however, is ascribed 12 major triumphs: “ Happy is he that hath the God of Jacob for his help, whose hope is in the LORD his God:  Which made heaven, and earth, the sea, and all that therein is: which keepeth truth for ever:  Which executeth judgment for the oppressed: which giveth food to the hungry. The LORD looseth the prisoners:  The LORD openeth the eyes of the blind: the LORD raiseth them that are bowed down: the LORD loveth the righteous:  The LORD preserveth the strangers; he relieveth the fatherless and widow: but the way of the wicked he turneth upside down.  The LORD shall reign for ever, even thy God, O Zion, unto all generations. Praise ye the LORD.”
He is Creator of all (verse 6), He keeps truth forever (verse 6), executes judgment for the troubled (verse 7), feeds the hungry (verse 7), frees the captives (verse 7), opens the eyes of the blind (verse 8), lifts the stooping (verse 8), loves the righteous (verse 8), preserves the strangers (verse 9), alleviates the orphans and widows (verse 9), turns the way of the wicked upside down (verse 9), and reigns forever (verse 10).
Actually, these underscore various aspects of Jesus Christ’s Second Coming. The Antichrist, an apostate king Israel demanded, has proved to be an utter disappointment: his promises were mere flatteries, worthless as he is. All the misery he caused, injustice he supported, and ruin he left behind, are reversed. Creation is liberated from Satan’s grip. The rightful King is now sitting on David’s throne in Jerusalem—His reign unending! “The LORD shall reign for ever, even thy God, O Zion, unto all generations. Praise ye the LORD.” source
