For my thoughts are not your thoughts, neither are your ways my ways, declares the Lord. For as the heavens are higher than the earth, so are my ways higher than your ways and my thoughts than your thoughts. Isaiah 55:8-9
This question is a bit philosophical.
It has been told so many times that we cannot fully understand God. We know our knowledge is so limited. And we have also stumbled upon problems in the Bible that we know not the answers to, like the problem of evil for example. We never get the whole picture of anything ever since we are not omniscient.
With all of those things considered, what gives us (flawed human beings) the right to even believe in anything? To teach anyone even anything at all? We might misinterpret things. And is it right to teach anyone something we might misinterpret when it comes to a matter of life and death? Why not teach them possibilities instead so they can choose them for themselves? Why not let us say that "we don't know", that things are not ever sure, that we don't fully believe in anything because we are not capable to know anything at all?
