The rate at which the weight of the word fades away from our heart is a reflection of how much keeping power we have,and to build the stable power for the word to constantly maintain it's weight in us it calls for consistent hearing to the point when your heart picks up the needed fervency to keep the word..a cold heart cannot keep the word(Hebrews 4:12). Have you been under a ministration and you are seeing decisions to make? Things to let go? And the moment you step out,you can't find that urge again (James 1:22) ...we would continue in this cycle until we have come to a place where our heart can self-generate fervency irregardless of feeling or monitoring but you have come to a place where within yourself you have a sense of duty to obey God.
