Christianity tells christians they should live righteous lives, and condemns _others_ who fail to do so, but does not teach its adherents how to live righteously.
It does no good to tell a man to live righteously if he genuinely has no idea how to rise above the lusts of the flesh/body.
There are verses, hidden in a mystery within the bible, which can lead a man to realize godliness within. But, that is not what gets preached from the pulpit on Sunday morning.
Even worse, Christianity is such a horribly hypocritical religion. It does not matter what you do, because Jesus will forgive you for it. Hence, according to Christian doctrine, there are no consequences of sin as long as you pray for forgiveness afterwards. That is 180 degreees from the doctine of Ma'at, or Karma.
Christianity is not so much a religion as it is a convenient excuse to _feel_ good about yourself irregardless of the presence, or absence, of love in your heart.
Christianity is not unique in this regard. You can find similar expressions of hypocrisy in other belief systems. It is this idea, often expressed even by those who hate and despise both the bible and Christianity, that _my_ God approves of the hate in _my_ heart, but condemns the hate in the heart of others.
