The spirit of humility is really the opposite of the spirit of independence. From our birth we have a really strong desire to think for ourselves, that is to have a knowledge of truth outside the paradigm of scripture. We do not think thoughts after God, but we think thoughts that are of a self gratifying nature. These thoughts really create their own reality. What happens is when we are meditating in this domain, we are in danger of a very earthy mindset. This mindset creates a life of fulfillment of our flesh, and creates an imagined world of self fulfillment. It is this natural process that is at rest in our thought life.
Because of our fallen state we are blind in our thinking to any divine knowledge. The knowledge we possess is very limited in its scope. We only think in terms of fulfillment of our lust by a learned process that comes from our imagination of what is true. That is why our best thoughts are very limited because they only go as far as our imagination. And if you can accumulate enough human experiences so that the imagination is a complex maze of idol musings, then your only going to make a mindset a complete self aggrandizement.

Once our minds are exposed to divine light, then we begin to see the real things. We were never created to have independent thoughts. We were never created to have independent solutions to problems. We were never created to solve things with our corrupted thinking. We were created to be taught how to think as well as what to think by a dependence on God at all times.By getting into the divine revelation we begin to have a spirit of humility. Our response in rejoicing  in divine knowledge is the natural way to fashion  a mind with a spirit of humility. Our minds should be saturated with the word of God so that the natural response should be a path way for further illumination. We are to meditate night and day, calling out to our Lord , nite and day. We are to respond to His word in the nature that His word comes to us. It is of a divine nature, and we are to rejoice in that divinity as if it were the most expensive jewelry of knowledge that we could ever possess. In  responding in like nature we begin to get our minds off of the earthly things and onto the eternal things. We begin to think correctly. In the mindset of eternal musing we develop a mind of humility. Because we begin to see ourselves in the mirror of His word and seeing ourselves as belonging to Christ we are seeing the face of Christ. We begin to see our real self in this glory to glory transformation of our minds. The more we respond to this illumination of Christ the more we will begin to think correctly and think humbly.
