Keith Simons explores Psalm 45, a beautiful depiction of a royal wedding that symbolizes God's perfect king, the Messiah. He emphasizes the king's beauty, grace, and righteousness, contrasting it with the fleeting beauty of earthly kings. The psalm illustrates the love between the king and his bride, representing God's people, and highlights the eternal nature of the king's rule. Simons encourages listeners to understand the deeper meanings of the psalm, focusing on the themes of love, honor, and divine kingship. Ultimately, the sermon reveals how the Messiah's reign is characterized by righteousness and everlasting glory.
