“The souls reside in a different dimension than flesh. So no it was not ‘time travel.”

Okay, thanks, your previous comment wasn’t quite clear to me.
What some others have said here is OT people were saved in their day by believing in God and His promise of a savior. If that were so, they’ve already had a chance to accept or reject salvation a very long time ago. Keeping that in mind, why would they be given a do-over, a 2nd chance, via Jesus preaching to them after they’ve died?
