On one level, our knowledge of God must lead us to know Him better, to love Him more, and to serve Him more effectively. Knowing God is not an end unto itself, but is the means through which our fellowship with Him is deepened, broadened, and strengthened. Our knowledge of God is the key to our relationship with Him.
On another level, our knowledge of God does not occur in a vacum, but is acquired while living a life in a fallen and broken world. Therefore it is to be applied to our life in the midst of our dealings with life, and our comings and goings in this world. Our knowledge of Him should effect the way we think, thereby influencing and guiding, being intertwined in every decision we make.
