The OT testifies about Jesus, Jesus *IS* salvation; therefore, the OT _is_ about salvation.
John 5:39 — “You study the Scriptures diligently because you think that in them you have eternal life. These are the very Scriptures that testify about me,”
"John 5:39 — “You study the Scriptures diligently because you think that in them you have eternal life. These are the very Scriptures that testify about me,”
Then why does the New Testament exist, if the OT is such a great and easily understood source????? I note that the Jews got it wrong right up to and past Jesus' crucifixion, INCLUDING most the Apostles (Emaus road narrative).
The simple fact is that both Jesus and the Apostles taught MOSTLY by the spoken and NOT the written word (Paul and John being notable exceptions). And they both taught from Jewish oral tradition, as well. So the existence of Christian tradition is a perfectly valid continuation.
The whole idea of "sola scriptura" is simply ridiculous on its face. We have God's WORD all around us (the physical universe) all the time, written in His Own Language and by His Own Hand, a few words and sentences of which we are beginning to understand.
