It is not lust alone that one should be afraid of in the life of the world. There is also anger. Anger arises when obstacles are placed in the way of desire.
If you feel proud, let it be in the thought that you are the servant of God, the son of God. Great men have the nature of a child. They are always a child before Him; so they are free from pride. All their strength is of God and not their own. It belongs to Him and comes from Him.
