A couple of weeks ago, while doing some work in my back yard, I was burning some branches (legally) on a burn pile.  I was amazed at how quickly and how hot it burned.  The flame rose a lot higher than I thought it would and it affected the trees around it.  To my surprise, the tree closest to the fire got singed pretty good.  What a great picture of the presence of God— if we get close to the holy fire of God we will be changed.  Psalm 39:3 says "my heart grew hot within me." While I meditated, the fire burned. Get close to the flame and allow God to set your heart on fire for revival.
