This was shared with Paul on his own blog, maybe not quite so succinctly, but still the same truth. This was his response. Pay attention to his scriptures:

And My Answer, which I will further embellish for your edification:

Now, we are communicating. Although the Church being in the OT is a possibility, we don’t need to believe (exactly) that in order to be able to see from Scripture that all saved from mankind have been placed in Christ. We know a few things that tell us that that is the case. (From Genesis) The Paradise where Adam resided was placed under the guard of Heavenly beings when Adam was evicted. Jesus then tells us that the dead are there (in the belly of the earth) and He and the thief will proceed there in death (to Paradise). Paradise is (then) moved into heaven following Christ’s resurrection. Paul was taken there to heaven in the Spirit (2 Cor. 12:2-4). And it was Paul who told us in Ephesians that Jesus led captivity captive (Eph.4). Those are facts that when put together tell us a lot. Further Peter tells us that the gospel was preached to the dead (1Peter 3:18-4:6). Jesus even said something to this effect (Jn 5:25). Some believe Jesus did this preaching when in Paradise and then delivered its captives — captivity led captive. This makes Paul’s proclamation of all men being “in Christ” viable and profound, and as stated the only means of resurrection to life eternal. What he says I think is clear. Every man died in Adam, and every man who is made worthy (See next post) is made alive in Christ. His preaching in paradise, while He was there was their means of deliverance. But maybe you can convince me otherwise?

Now To Some additional Scripture for my bloggers:

Revelation 2:7 ‘He who has an ear, let him hear what the Spirit says to the churches. To him who overcomes, I will grant to eat of the tree of life which is in the Paradise of God.’ (NASB1995)

Ask yourself this question: Did Jesus announce His Coming to Israel in their and our Old Testament Scriptures? We like to say that they were saved by their trust in His promises to them and in His future coming (remember He is that Word which they heard and recorded for all to here), and thus they were saved by Him, and when they died they went to a captivity in Shaol where they awaited Him their deliverance. And what did He then do when He went into the belly of the earth for three days and nights? Did He complete what He had stated to the Leaders in Israel when He came?

John 10:14 “I am the good shepherd, and I know My own and My own know Me, 15 even as the Father knows Me and I know the Father; and I lay down My life for the sheep.

These sheep of which He speaks are the sheep of Israel’s fold, but there is more:

John 10:16 “I have other sheep, which are not of this fold; I must bring them also, and they will hear My voice; and they will become one flock [with] one shepherd. (NASB1995)

Can we honestly ignore this truth spoken from the mouth of the Word Himself, who expresses to us only what He hears the Father say?

Wisdom sought of the Lord, the writer of the proverbs says that it comes to bring us understanding. How can we be wise if we go against the understanding of His truth?
