Biblically speaking, not very many people at all would have believed Jesus if not for seeing his miracles, and the miracle of his life.During the last two thousand years the overwhelming mass of people who have believed in Jesus have never seen Him, on this side of the veil.
That's correct.YLTJohn 2029
Jesus saith to him, `Because thou hast seen me, Thomas, thou hast believed
; happy those not having seen, and having believed.
The verse mentions two groups of believers. The red group is the group you mentioned.
But what about the blue group? Is there only one person (Thomas) in that group?
Imo, Jesus wasn't just speaking to Thomas. The verse is a teaching for whole mankind.
Then what exactly was that 'blue teaching'?
Personally I think Jesus was not pronouncing doom on Thomas.
Jesus called Thomas a believer.YLTActs 1631
and they said, `Believe
on the Lord Jesus Christ, and thou shalt be saved
--thou and thy house;'
So everyone that believes is saved. Thomas didn't even believe by seeing. He needed to touch Him to believe.
But right now we can only believe without seeing, hearing or touching. --> Our first opportunity so to speak.
But when we can believe because we touch like Thomas? -> Our second opportunity.
I think that happens at the "every knee shall bow" event...
BTW the other apostles were not real believers either. They traveled 3 years with Jesus. They saw many miracles. And still they didn't believe He would be resurrected. Not even the women who reported it were believed.
Thomas needed seeing and touching. The others needed seeing. Far more as we have right now. But they are all saved.
