The warm heart. I would rather have a warm heart towards others than a cold doctrinaly stiff heart / neck. This is not always the case with me. However first steps are seeing the lack and then remain sensitive to that need for mind/ heart renewal in that area.
The mind/heart renewal comes by continuously being washed by the pure milk of the word. By continuously acting upon the washing of the word. By continuously praying about the washing your getting.
This process can only be undertaken by one who has been first born again/saved.
To attempt the process without having the Spirit of Christ in us will only be an excercise in law, not a growth in grace!
Also I think most of us are drawn to the warmth more than the cold.
