...that the answer to questions about God and Jesus and the Bible would give you insight into how a christian can believe in that which he/she does not physically see? I see lots of questions about how could God do this or how can you provide proof of this, etc...we (christians) have said over and over (and scripture clearly confirms it-see reference below) that it is impossible to grasp these spiritual, supernatural things without the Spirit of God in you, guiding your thoughts. Of course you cannot see it! Neither could I or any christian until faith (trust) came into our hearts. Even then, in the beginning, we did not see or understand most of it. In time, with study and prayer (basically one word...Obedience) we grow spiritually and understand more, just as any child does after he/she enters first grade, and so on. Maybe you do not hope for insight. Maybe you just ask out of curiosity and never gain ground into understanding, and that's enough for you. I truly think there are some that yearn for God and yet refuse the simple plan He has ordained. "Trust me first, then I will give you eternal riches." It is so very simple and yet so beyond us. We have to admit we are helpless. We have to own our moral error (sin). We have to bow to the will of another, one we cannot see. These acts of surrender are the barriers we will not succomb to, because it involves admitting we are inadequate. Interesting that this one feeling, inadequacy, is in my opinion the gist whereby most relationships fail. We all hate the feeling of 'I am not good enough as I am.' It is true of us all. We are not...spiritually speaking. And if eternity is a reality, as we (christians) know it is, as God is, then our spiritual health is all that matters. God can and will cover all the other bases.
See for reference (if so inclined) 1st Corinthians 2:14.
