What does Psalm 45:10 mean?

The psalmist challenges the prospective bride of the king (Psalm 45:1, 9) to "forget" her people and her father's house. This does not mean to erase them from her memory. Instead, it means to set them aside in favor of her marriage. She was about to begin a new relationship. These words are reminiscent of Genesis 2:24, "Therefore a man shall leave his father and his mother and hold fast to his wife, and they shall become one flesh." Of course, the relationship is the same for the wife. She, too, must leave her father and mother and hold fast to her husband.

What was true for the king's bride is also true for the Church, Jesus' bride. Christians should renounce their former love of the world. The apostle John writes: "Do not love the world or the things in the world. If anyone loves the world, the love of the Father is not in him" (1 John 2:15). The apostle Paul reported sadly that one of his coworkers had dropped out of missionary work because he loved the world (2 Timothy 4:10). Paul testified that the cross had severed his relationship with the world (Galatians 6:14).
