I'd like to know what you mean by 'valid' and which parts of the bible are included.
Christians believe that the Bible is a book written
by men who were inspired by God's
Holy Spirit that gave them instruction in their writings. The Holy Spirit thus created the Bible as the means for us to know who God is and how we can receive instruction from him. The early church composed the Bible from hundreds of ancient writings, with the help of the Holy Spirit.
In order to prove the Bible is valid, you need to know how to see "the Holy Spirit's fingerprints" as it were. The Bible is also without flaw or contradiction, even though it might appear to be at times.
Do all Christians believe this? No.
Should they believe it? Yes, but only if we can help them to understand.
Can a child have a 'genuine saving faith in Jesus'? If not, at what stage is it possible/available?
I'm curious because I was brought up Christian (Catholic), and - though I don't really remember - it's possible that at one time I may have believed in Jesus as much as, or perhaps more, than I believed in the other imaginary beings that kids were encouraged to believe in. If that was a genuine saving faith, then all bases are covered, no need for Pascal's Wager
- but, as I said, I don't recall...
2 Corinthians 7:10 says, "For godly grief produces a repentance that leads to salvation without regret, whereas worldly grief produces death."
Let me put it to you this way. God loves you very much and he's given you the Bible to help you understand who he is. God has even made humanity in
his image (meaning a mind and personality). Still, humanity is a fallen race because we are corrupt and sinful, but God loved us enough to provide us a way out.
"Saving Faith" is a point in your understanding of God that's available to anyone of any age. After you begin to realize what sin looks like through God's eyes, and you've come to believe that Jesus is the person he said he is, this is when saving faith happens. You begin to realize the sins you've committed (even the small ones) make you deserving of God's wrath, and you also firmly believe that Jesus was sent by God to be the ransom for your sins. If, during one such moment you willfully confessed your guilt and sorrow and then asked Jesus to forgive you, then you are Saved-And-Always-Saved.
Now, I don't pretend to know whether-or-not you had saving faith at a young age, but I will say this. A child can develop
"belief" with help from their parents, but ultimately they develop
"faith" by themselves, when they reach the conclusion for themselves that God is real. (That's the definition of faith).
Now, I very much admire Pascal's Wager. And maybe you were saved as a child, FrumiousBandersnatch, but there is more to Eternal Security than you might realize. There are, indeed, people going to heaven who later lost their faith, but God rewards people in heaven differently depending on how faithful they were on earth. I have scriptural proof of this doctrine also.
But the ultimate point of my posts is to help, because I'd like you to know FrumiousBandersnatch that you
can go to heaven and rest assured that you won't loose your salvation. I won't force you, but I'll keep giving you answers if that's what you want.
So someone stayed awake and saw God?
No, no. In the story, Abraham fell into a deep sleep and dreamt that God went in between the animals to confirm his promise with Abraham. More specifically, Abraham saw a furnace which represents the
presence of God (because God does not have a physical form). But he knew it was God because God gave him these instructions when he was awake.
