no more separation

In the Jewish mindset, death was a separation, not a ceasing of existence.  In death, the soul, still alive, was separated from the body.

When the Bible says that we were all born dead, this is what it means: we were born separated from God because of sin.

During Jesus' ministry, we have several accounts of him raising people from the dead, like in Luke 7:

11 Soon afterward, Jesus went to a town called Nain, and his disciples and a large crowd went along with him. 12 As he approached the town gate, a dead person was being carried out—the only son of his mother, and she was a widow. And a large crowd from the town was with her. 13 When the Lord saw her, his heart went out to her and he said, "Don't cry."  

14 Then he went up and touched the bier they were carrying him on, and the bearers stood still. He said, "Young man, I say to you, get up!" 15 The dead man sat up and began to talk, and Jesus gave him back to his mother.

As we read this in the modern age, we tend to be a little more amazed (or more skeptical) of the biological side of this account.

But the original readers would have been more amazed with the spiritual side of it.

By raising people from the dead, Jesus demonstrated that he had the power to overcome this separation.

He has the power to overcome the separation of those who die - to reunite the soul with the body.

He has the power to overcome the separation of those who are born dead - to reunite the sinner with the Father.

And he's been raising people from the dead ever since.

From the same chapter:

16 They were all filled with awe and praised God. "A great prophet has appeared among us," they said. "God has come to help his people."

God has come to help his people.
