Do you need a high IQ to be a Christian?

I mean I know the answer is obviously no, but I'm just wondering, how is one able to be a Christian if 1) they are illiterate so they can't study the Bible (not all preachers teach the Bible accurately or 2) Just have a low IQ and therefore can't understand the Bible? As it is it's a little hard for those with a high IQ lol...
