Ezekiel 34

I will establish one shepherd over them, and he shall feed them—My servant David. He shall feed them and be their shepherd.  And I, the Lord, will be their God, and My servant David a prince among them; I, the Lord, have spoken. vv.23-24

Read chapter 34
The famous well known King David is back!  This chapter takes place hundreds of years after King David's death yet the Lord says that David will be the prince over Israel.  So how can that be?  This must be a future time when David is raised and all Israel is gathered together again.  We know that when the Kingdom comes all Israel and believers will be raised.  That time will still have leaders as we know the twelve apostles will sit on twelve thrones judging the twelve tribes of Israel.  Jesus will take the place as King of kings and be the one and only ruler in the earth, but there will also be a prince under Him and that prince is named here- David.  Some will say that David here means Jesus, but in verse 24 it clearly notes two rulers- Jehovah their God and David a prince.  
David is not just a fictional character of stories of the past, but we will one day seem him among us and as a leader over us, following a leader that is described as a man after God's heart.  What other human leader would you want in God's government?!
