What does Psalm 45:16 mean?

This verse carries the psalmist's blessing on the king and his queen as they leave the palace. He addresses the king by observing that the king's forefathers were great, but his descendants will be greater. The king will place them in his kingdom as princes. Because this wedding song (Psalm 45:1, 9) also parallels the ministry of Christ (Psalm 45:6–7; Hebrews 1:8–9), it's possible to see hints about aspects of the end times.

When Jesus sets up His kingdom on earth, He will grant positions of authority to His faithful servants. In His parable of the talents, Jesus commented that the faithful servant's master said, "Well done, good and faithful servant. You have been faithful over a little; I will set you over much. Enter into the joy of your master" (Matthew 25:23). Second Timothy 2:12 promises, "If we endure, we will also reign with [Jesus]." Jesus promised the church at Thyatira: "The one who conquers and keeps my works until the end, to him I will give authority over the nations, and he will rule them with a rod of iron" (Revelation 2:26–27).
