That is the true teaching of Christ: how to use the lower nature to rise towards God
"The Creator wants human beings to develop with both of their natures – the higher and the lower – for they are complementary, as are spirit and matter. And that is the true teaching of Christ: how to use the lower nature to rise towards God.
But what has the Church done? Instead of teaching people this truth and giving them methods to put it into practice, it has mostly spread a philosophy and a morality based on disgust and condemnation of the instincts. And so Christians still have a lot to learn and understand before they can become true disciples of Christ and, quite simply, develop harmoniously as human beings."
