The truest definition of humility is not necessarily turning the other cheek whenever someone does you wrong, because God expects that you will defend yourself, and he also expects you to defend the kingdom of God, and the people of the kingdom. True humility is being willing to surrender your will to the will and purpose of the indwelling Holy Spirit Of God.
It is the Holy Spirit Of God to whom you must submit, not the neighbor who repeatedly does you wrong. It is the Holy Spirit Of God whose advice you must seek, not the friend who ultimately might betray you. When you are willing to subjugate your will, and your desires to that of the Holy Spirit Of God, only then can you be deemed to be truly humble.
The Lord God Almighty El Shaddai
