I would like to challenge all the christians to think like
atheists.
I challenge them to question the existance of God.
I challenge them to think that there's a possibility that God don't
exists.
I challenge them to admit that they can't prove God does
exist.
I challenge them to ponder whether God really answer their
prayers.
I challenge them to question whether their lives are determined by
themselves or God.
I challenge them to look back their lives and ask whether God has
done anything to them.
I challenge them to use some logic and intelligence to think about
their religion and whether it hold truths.
