Those are weasel words. If they dont know Christ and put their faith in Him they will NOT be saved.
John 14:6 Jesus saith unto him, I am the way, the truth, and the life: no man cometh unto the Father, but by me.
Acts 16:31 And they said, Believe on the Lord Jesus Christ, and thou shalt be saved, and thy house.
Acts 4:12 Nor is there salvation in any other, for there is no other name under heaven given among men by which we must be saved.
So then you assert that nobody from the Old Testament was saved?
“Acts 4:12 Nor is there salvation in any other, for there is no other name under heaven given among men by which we must be saved.
That right there one statement tells us a multitude of truths which we can find in the OT.
