This is my Desire, Consume me Like a Fire.

Begins with one match, but a prior building was required. The bark allows quick flames to burst: a conference, words from God, etc. The kindling does just that, kindle (def: to cause to begin burning): worship, prayer, etc. The logs allow for a lengthy, steady burn: daily quiet time, secret prayer life, etc. The logs then turn to coals and create an ever burning fire. Sparks can fly out and cause the fire to rapidly spread; this ultimately being the goal. All parts necessary for the fire to ignite, but the match can only be provided by the Fire Himself. Caution must be used, however, for a fire, left untended, dies quickly.
