When a blade is very sharp, it becomes easier to cut without using much strength. It is the same in the spirit, when your spirit is very sharp, you get with simplicity results which other people struggle for. Man is what he thinks about all day long, where his mind goes, his life will follow. The spirit of man will always take the shape of his thoughts, and the shape of this thoughts will always take the shape of the information which he feeds his mind. God is not necessarily concerned by the wrong thing you did, because he knows that the problem is not in what you did, but in the thing which caused you to do what you did. Man’s actions are motivated by his thoughts, so in changing man, the Lord seeks to deal with our minds, and not with our actions. Your mind is very important to God, this is why he told us renew our minds with his Word, Romans 12:2 "And be not conformed to this world : but be ye transformed by the renewing of your mind, that ye may prove what is that good, and acceptable, and perfect will of God.”
Paul writing to Timothy said, “Study to show thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth” (2 Timothy 2:15). When you feed your mind with the Word, your mind will take the character of God, and your spirit will take the same shape. Colossians 3:10 says, "And have put on the new man, which is renewed in knowledge after the image of him that created him". The power of God works better with a spirit which is transformed into the shape of the Word. The power of the Holy Spirit works from within us, and for it to be activated there must be a fellowship between the Holy Spirit and our spirit through the Word. 2 Corinthians 3:18 Says, "But we all, with open face beholding as in a glass the glory of the Lord, are changed into the same image from glory to glory, even as by the Spirit of the Lord". Christianity is the working of the Word of God in our spirits by the Holy Spirit, a fellowship of Spirits through the Word.
