Raised from the Dead, Descended from David

Remember Jesus Christ, raised from the dead, descended from David. This is my gospel. 
     - 2 Timothy 2:8

Paul gives his young friend Timothy a neat summary here of the gospel. It may not be how we usually think of the gospel, but it's still what Paul calls "the gospel." 

There are two parts to this gospel. The first is that Jesus is "raised from the dead." He's alive - death did not win. That's something only God can do, and is indeed a validation of his divine nature.

"Descended from David" is the other part of the gospel. I take that to mean that he was fully human. He was part of God's story of redeeming humankind that's been going on throughout history, and Jesus brought it to conclusion by being born in that stable in Bethlehem on Christmas morning.
