God chose to reveal himself in that way to those of us that are Christians. Does God have other ways of revealing himself, or does everyone else go to hell?
I understand your point, but let's focus on the topic at hand -
@Robert Pate's statement about the purpose of the Bible. It's important to note that Robert is using the Bible to support his argument, indicating that he views it as a trustworthy source of information about God's will and plan for salvation through Jesus Christ. Whether or not someone has access to the Bible is not relevant to this discussion.
Yes, as Robert pointed out, God has other ways to reveal himself to everyone else. Robert cited Romans chapter one, wherein Paul indicates that creation itself proves the existence of God and his glory. They are without excuse who invent gods of their own.
I would also point out Paul's word in Hebrews chapter 11, wherein Paul asserts that God is granting justification to those who know that God exists and that he is a rewarder of those who seek him. That's it. 1) know God exists, and 2) know him as one who rewards those who seek him.
In other words, though Jesus Christ is the basis of salvation, knowing his name and his story is NOT essential. After all, the Patriarchs didn't know the name of the savior and had no knowledge of his ministry or his death on the cross. And yet God will save them. Why? Because had they known his name and heard the gospel story they would have believed it since they have a heart for God and the truth. In my view, the same is true of those living in remote places on earth who know God exists and that he rewards those who seek him.
You know why Jesus gave the Holy Spirit to the Apostles to help them. The Holy Spirit can get to places where evangelists can't reach.
