I don't agree that large numbers of Jews will come to Christ which will be proof the current age is nearing its conclusion.
I don't think I said "proof that the current age nearing its conclusion," but only that "I think ~ don't know this to be true" (I was sure to enter that little qualifier) "that will be an indicator that the fullness of the Gentiles has been brought in." That can't be proven, and you may or may not agree with this, but it can't really be refuted, either. And I did classify all that as a relatively minor point that can only be speculated on.
And I would add this as an aside regarding "nearing its conclusion." There are two perspectives on that, I think, God's and ours. :) It is all "near" as far as God is concerned; to Him, as David says, "a thousand years in (His) sight are but as yesterday when it is past, or as a watch in the night." But to us, that's not so much the case. :) It's often a very hard thing to wait upon the Lord... :)
I believe Jews and well as Gentiles have been entering the Kingdom of God throughout this age of Gospel grace.
So do I, and I was clear in stating that. But, near the end of the Church Age, I think many ethnic Jews will come to the Lord in a short period of time. Again, that's speculation on my part, but it seems to me consistent with what Jesus says in Matthew 24. Yes, He's talking about the entire Church Age, but I see a ramping up (to put it mildly) near the end, or at least as we get ever closer.
Because if I'm rightly understanding Scripture since Christ's cross and resurrection there is no distinction between the two. When we are in Christ the wall of separation is gone, and there is neither Jew nor Gentile, but Christians of all the nations of the world.
I agree. But I think it not to be so simple. Not that you're over-simplifying it; I don't mean to insinuate that. But I think it's a different thing to say the Gospel is open to all, regardless of ethnicity (so in that sense the wall of separation is indeed gone) and then
to some extent (not that you mean to do this, but...) soft-pedal the distinctive Jewish race, even in the eyes of the Lord, which of course we cannot see through but only acknowledge, as Isaiah does, that His thoughts and ways are different than ours (Isaiah 55:8-9).
Again, grace and peace to you!
