I agree with you that the OT saints were saved just as we are now, all saved by the Cross of Christ on our behalf, and the saved of Israel were part of the NT Church, but the NT church was not in the OC, as that group was not here until the promised Messiah came and died and rose again, and the coming of the Holy Spirit in a new way at Pentecost..But don't you see that the truly saved in the OT were saved by the same blood of Christ that we are saved by today? The church, the bride of Christ is, I repeat: the saved of all ages. The saints of the OT looked forward to the Messiah, the Suffering Servant of God who would die for their sins, the NT saints look back to that same Messiah, who died ONCE FOR ALL, who came to redeem to Himself ONE people. The church. Hallelujah.
