but actually i like your 3:8. The OT Jews thought Genesis was teaching all nations will be blessed by physical decendents of Abraham

The physical descendent of Abraham that blessed all men was Christ..Remember that the entire OT is a prophetic revelation to the jews ... as scripture tells us the jews were/are blinded to the spirituality

Jesus said the entire OT..law and prophets was about Him

[one Lord one faith one baptism]

you are correct, but the OT Jews did not understand this until Jesus and Apostles brought forth new doctrines.

was John 1 taught in the OT?

and the Word became flesh and dwelt among us.

NEW DOCTRINE
