Imo, everyone that believes in the Bible is ignorant on the subject since it is impossible for them to know if God exists or not. So to say matter-of-factly that he does exist and the Bible is gospel, etc. means you are taking a leap of faith...thus, you do NOT know...you only believe. So you are ignorant (you lack knowledge) on the subject. You have zero scientific proof that God exists - it is purely an emotional decision...that ever-popular 'leap of faith'.
I can believe that little green men live underground on Mars...but since I cannot know, I am ignorant on the subject...no matter how much I believe.
Believing in something does not make it real...it is just belief.
