A good reminder from our old friend C.S. Lewis:
It is, of course, quite true that God will not love you any the less, or have less use for you, if you happen to have been born with a very second-rate brain. He has room for people with very little sense, but He wants every one to use what sense they have. … 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.
