Yes. Adam and Eve were flesh-and-blood people, like you and I. So were all the historical people in the Bible, which was written (put pen to paper) by men, but written by God because He gave them the words to write. "For this cause also thank we God without ceasing, because, when ye received the word of God which ye heard of us, ye received it not as the word of men, but as it is in truth, the word of God, which effectually worketh also in you that believe." (1 Thessalonians 2:13)
Another thing I want to address is that you all are always bringing up the bad things that professing Christians have done, and then using it as a proof against Christianity. In logic that's called Ad Hominem, and it's a fallacy. Just because sinful men who call themselves Christians (who may not even be regenerate) do bad things, does not discredit the truth of the Scriptures.It just goes to prove that God is very merciful that He will save even the worst of men, if they repent. The Bible is historically, mathematically and scientifically accurate and has withstood the test of time and come out on top of all criticism, as even Times Magazine said: "After more than two centuris of facing the heaviest scientific guns that could be brought to bear, the Bible has survived, and is perhaps the better for the siege. Even on the critic's own terms -historical fact- Scriptures seem more acceptable now than i t did when the rationalists began the attack." (Time Magazine "How True Is the Bible?")
If the bible has an answer to everything, where does it tell me next week's lottery numbers?
The Bibile does not have specific references to everything. But it has principles, in it which apply to every area of life. In the case of gambling, we can apply 1 Timothy 6:10, Hebrews 13:5, Proverbs 13:11, Proverbs 23:5 and Ecclesiastes 5:10. Also we can apply the commandment that 'Thou shalt not steal" in the context that gambling takes money from one person and gives to another. Ther are many other scriptures that we could also apply to gambling.
Again, the Bible is perfect, the Word of God. The 66 books and those 66 books alone are the infallible Scriptures, because those are the books that God inspired.
