IMO, the Acts 3quote above makes more sense seeing Jesus being sent as 'literal' since it talks about heaven receiving Him. I hadn't thought of Israel's salvation as happening before Jesus' return.Some might argue that Israel rejected the offer and the Gospel went to the Gentiles to provoke them to jealousy as a result, resulting in a different end times scenario than what Peter offered, but I am not sure. The salvation of Israel is still prophesied.One scenario is the second coming takes a while to complete and Israel repents then, when they literally look on Him Whom they have pierced. Revelation refers to this verse in chapter 1, I believe, in connection to Christ's return.
