Why is it you refuse to answer a simple question: was Paul's gospel for Adam and Eve and all that lived and died before the flood? A simply yes or no would suffice.
I have avoided the question up to this point because you are attempting to produce a diversion in order to avoid Paul's warning in Galatians 1:6-9.
The answer is simple.
We find the promise of the Messiah in Genesis 3:15, when God told Satan of the one who would destroy him.
Gen 3:15 And I will put enmity between thee and the woman, and between thy seed and
her seed;
it shall bruise thy head, and thou shalt bruise his heel.
It was their faith in the coming Messiah that saved them.
Heb 11:1 Now
faith is the substance of things hoped for, the evidence of things not seen.
Heb 11:2 For by it the elders obtained a good report.
Heb 11:3
Through faith we understand that the worlds were framed by the word of God, so that things which are seen were not made of things which do appear.
Heb 11:4
By faith Abel offered unto God a more excellent sacrifice than Cain, by which he obtained witness that he was righteous, God testifying of his gifts: and by it he being dead yet speaketh.
Heb 11:5
By faith Enoch was translated that he should not see death; and was not found, because God had translated him: for before his translation he had this testimony, that he pleased God.
Heb 11:6 But
without faith it is impossible to please him: for he that cometh to God must believe that he is, and
that he is a rewarder of them that diligently seek him.
Heb 11:7
By faith Noah, being warned of God of things not seen as yet, moved with fear, prepared an ark to the saving of his house; by the which he condemned the world, and became heir of the righteousness which is by faith.
Heb 11:8
By faith Abraham, when he was called to go out into a place which he should after receive for an inheritance, obeyed; and he went out, not knowing whither he went.
Heb 11:9
By faith he sojourned in the land of promise, as
in a strange country, dwelling in tabernacles with Isaac and Jacob, the heirs with him of the same promise:
Heb 11:10 For he looked for a city which hath foundations, whose builder and maker
is God.
Heb 11:11
Through faith also Sara herself received strength to conceive seed, and was delivered of a child when she was past age, because she judged him faithful who had promised.
Heb 11:12 Therefore sprang there even of one, and him as good as dead,
so many as the stars of the sky in multitude, and as the sand which is by the sea shore innumerable.
Heb 11:13
These all died in faith, not having received the promises, but having seen them afar off, and were persuaded of them, and embraced them, and confessed that they were strangers and pilgrims on the earth.
Heb 11:14 For they that say such things declare plainly that they seek a country.
Heb 11:15 And truly, if they had been mindful of that
country from whence they came out, they might have had opportunity to have returned.
Heb 11:16 But
now they desire a better country, that is, an heavenly: wherefore God is not ashamed to be called their God: for he hath prepared for them a city.
(That city is New Jerusalem, which is now above.)
It is the same city we will inherit.
Gal 4:26 But Jerusalem which is above is free, which is the mother of us all.
Now, why don't you explain to us how you can get your doctrine to agree with Galatians 1:6-9...
