I see now, you were not deluded by Christianity, but religion. Big difference!
As well, being Christian, certainly does not mean that we throw our common sense out the window. Common sense is a God given gift. Now where does the bible say to throw that sense away.
The Holy Spirit is our helper, guide, comforter etc. Which means that true seekers of God's word, that are Holy Spirit filled can read the Bible and and have His help to understand the scriptures.
