People that are more knowledgeable than me can give a deeper or even better answer on this, but I will write one of the best answers I personally know. :) Let's just think about this logically... If the Bible is man-made, why does it go against man's desires? The Bible teaches that you simply cannot earn your way, or be good enough, to get to heaven. Good deeds will not get you to heaven.

"Then Jesus told his disciples, 'If anyone would come after me, let him deny himself and take up his cross and follow me.'" Matthew 16:24 Jesus taught that sin is not just physical actions. Read Matthew 5:21-30 . Read how Jesus says that murder begins in the heart, if you so much as hate someone you are guilty of murder. (Also read 1 John 3:15 .) Who wants to hear that ?
