Hi Thinker!Looking up,
You have to go back to John 3 when Jesus said that "God so loved the world that he gave His only begotten Son, that whosoever believes in Him has eternal life". The present tense has eternal life is the result of believing in Christ whom God gave. Therefore, there was no salvation before Christ died. If so, then it would not have been necessary for Christ to die.
No one who believed before the cross was saved without those who believed after the cross. Speaking about all pre-cross saints Hebrews says this:
"And all these, having obtained a good testimony through faith, did NOT receive the promise, God having provided something better through us, that they should not be made perfect apart from us" (Hebrews 11:39).
It says that they merely had received a "good testimony" through faith. But they did NOT have the promise. It says so. And it says that they had to receive the promise through post-cross saints and not apart from them.
First, your understanding of the term "regeneration" is incorrect. Regeneration does not mean "re-birth". It means to be "born from above". A regenerated man is simply a man who has been born from above and he is born from above at his pyhsical birth. Paul taught this principle in Galatians 4. He said that Isaac was born according to the spirit when Sarah gave birth to him. Paul likened Isaac's physical birth of Sarah as being born from the Jerusalem that is from above.
Conversly, Ishmael was born according to the flesh from his physical birth of Hagar. Paul likened his birth to being born of the earth, that is from beneath.
Jesus said that a man is either born from above, that is, according to the spirit or he is born according to the flesh. Paul said that this occurs regarding each man when he is born. In other words, men are born regenerated or unregenerated and it is irreversible. But the man who is born regenerated must still believe no matter what and he necessarily will believe.
Second, your supposition that a man must be regenerated in order to author Scripture cannot stand. God spoke His word through a jack-ass.
If we are born regenerated, then who is the old man that is crucified with Christ?
