Does the Bible provide clear teachings?¶
And reality (God) is unreachable to human mind. No human can validly say “I know God”. A person who says “I know God” is a liar. A teaching that claims “We know God” is sectarian because it separates its followers from those who don’t agree to the teaching. The Bible expresses this by saying that God’s name is holy (see The name of God).
So don’t mix up “God” with “my image of God” or “our teaching about God”.
The Bible contains many stories about people who trusted in a right image of reality (God) despite the fact that it differed from the established image, and who then turned out to be right, sometimes only after their death.
And the Bible also contains many stories about people who trusted in a wrong image of God (reality) and then turned out to be wrong, sometimes only after their death.
I love to say that the Bible is clear about one thing: that nothing is clear.
