A physical salvation from their enemies so they could be a people of God and serve Him without fear. For hundreds of years they’ve been under the control of other kingdoms. They were awaiting their promised King to restore Israel to her glory. What they didn’t realize, because it was hidden from them, is this King would first come to die for their sins. They could not inherit the physical kingdom in sin. They had to be delivered from their sins, then the physical could be given.
Paul said the believing elect were receiving the promises through the gospel:
(Rom 11:7 What then? Israel hath not obtained that which he seeketh for; but the election hath obtained it, and the rest were blinded)
If the elect "hath obtained it" how can it be said that what was being sought was a physical kingdom?
