Psalms 88

Psalms 88:4

"I will establish your seed for ever, and build up your throne to all generations. Pause."
Wasn't David's throne unoccupied for a while?

A common objection claims, "God promised there would always be a Davidic king, but the Davidic line ended with Zedekiah and no king returned to the Davidic throne for 450 years. Moreover, what descendant of David is now ruling in the Middle East?"

To begin with, Jeremiah 33:17 only says that David will always have a descendant available to occupy his throne. Psalm 89, also referred to, only says that his throne will always be established, not always occupied. To illustrate this, let's use an example from US Civics. Occasionally, one of our Presidents dies in office. At that time, there is no president until the VP is sworn in. During that time, however, the office of the President still exists, even if no one is occupying it, and even though there is someone waiting to take it. In Luke 1:32, the angel tells Mary that God will GIVE Jesus David's throne, not RE-ESTABLISH it. And of course, Christ occupies it forever.
