Here's an interesting verse in Romans 11 that ties the two events together, Israel's return to Christ, and Life from the Dead:
"Israel’s Rejection Not Final
11I say then, have they stumbled that they should fall? Certainly not! But through their fall, to provoke them to jealousy, salvation has come to the Gentiles. 12Now if their fall is riches for the world, and their failure riches for the Gentiles, how much more their fullness! [NLT: "Now if the Gentiles were enriched because the people of Israel turned down God’s offer of salvation, think how much greater a blessing the world will share when they finally accept it.]
13For I speak to you Gentiles; inasmuch as I am an apostle to the Gentiles, I magnify my ministry, 14if by any means I may provoke to jealousy those who are my flesh and save some of them. 15For if their being cast away is the reconciling of the world, what will their acceptance be but life from the dead?"
