The 45th psalm is a beautiful Messianic psalm, speaking prophetically of the coming Messiah, the Lord Jesus Christ. In fact, the psalm is quoted by the writer of Hebrews, calling Him "God," and promising not only eternal remembrance, but also everlasting dominion: "But unto the Son, he saith, Thy throne, O God, is for ever and ever: a scepter of righteousness is the scepter of thy kingdom" (Hebrews 1:8, citing Psalm 45:6).
But the writer also said He would be remembered in all generations. That has proved true, so far! As others have frequently noted, this man lived on earth only thirty-three years, never traveled more than a few miles from His home, never wrote a book, never raised an army, never ruled over so much as a village, let alone a kingdom, never married or had children, never enrolled for any formal education, and finally was executed as a criminal.
Yet He has, indeed, been remembered through all generations following His all-too-short career two thousand years ago--and remembered with love and deep reverence and gratitude by millions of people in all nations ever since. Furthermore, though He never wrote a book, others have written innumerable books about Him, while another psalmist assured us that His words would also be preserved "from this generation for ever" (Psalm 12:7).
And all this has come to pass! Herein is a marvelous thing! Indeed, He was, and is, God and this was demonstrated by His flawless character, His amazing teachings, His unique miracles, His volitional, sacrificial death, and His mighty defeat of death itself by His bodily resurrection and ascent into heaven.
