Humility is the enemy of sin. Humiliation and pride are the strategies of the spirit and the flesh as they wage war on one another. The one thing that humility and sin have in common is that the greater degree a person has of either in their character, the less recognition or sense of its presence they have. In fact, there is an almost inverse relation and a sort of mirror reflection that contrasts that person who is exceedingly sinful yet who perceives in himself great humility, and that person who is exceedingly humble yet perceives in himself great sin.
This inverse effect can be seen in the same person before and after Christ (for a great example of this, see John Bunyan’s “Grace Abounding to the Chief of Sinners”); it can also be seen between people contrasted against one another like Saul and David in the books of Samuel and Kings. It is summed up nicely by James and in the Proverbs: “God opposes the proud, but gives grace to the humble.” While our flesh is perfectly capable of manifesting pride and sin, it can never manifest humility–for that is the fruit of its mortification and is only given to us by the Spirit.
