One reason why it needs no special education to be a Christian is that Christianity is an education itselfDallas Willard observes in Knowing Christ Today that "One effect of the displacement of faith from knowledge... is that many people now believe you do not need to think deeply and carefully to follow Christ"
Willard quotes C. S. Lewis:
"God has room for people with very little sense, but He wants every one to use what sense they have. The proper motto is not 'Be good, sweet maid, and let who can be clever,' but 'Be good, sweet maid, and don't forget that this involves being as clever as you can.' God is no fonder of intellectual slackers than of any other slackers. If you are thinking of becoming a Christian, I warn you, you are embarking on something which is going to take the whole of you, brains and all…. One reason why it needs no special education to be a Christian is that Christianity is an education itself." (From Mere Christianity)
