Whenever I have been camping and return home the first thing I want to do is take a shower to wash off the filth. Everyone I know washes their physical bodies on a regular basis. If we don't, we begin to become filthy. Are we as anxious to wash off the filth our spirits must experience from being out in the world? This cleansing takes place as we read our scriptures and, the same as our physical bodies, if we avoid reading our scriptures our spirits can begin to become filthy. Scripture reading can also allow the living water of God's love and his gospel heal our spirits and hearts. We have all been wounded in one way or another throughout our lives. Scripture reading can cleanse our wounds to help begin the healing process and avoid the spiritual "infections" of anger and bitterness that sometimes accompany hard times.
Jacob 2:8 reads "And, it supposeth me that they have come hither to hear the pleasing word of God, yea, the word which healeth the wounded soul." I know from personal experience that reading from the scriptures can bring an added measure of the spirit into your life which can quench your thirst and heal your soul.
