Our Scripture readings, this morning, are 1 Kings 19:19-21 and John 6:66-68. In the I Kings reading Elijah has put his "mantle" on Elisha. Elisha "returned to his oxen, and slaughtered them. He used the wood from the plow to build a fire to roast their flesh." (v. 21 New Living Translation) Elisha then feeds the people and leaves to follow Elijah. In the Gospel reading Jesus has been explaining about being the "bread of life". He has answered questions, explained people "can't come to me unless the Father gives them to me." (v. 65 New Living Translation) This causes a number of people to leave, to stop following Jesus. So Jesus asks the Disciples "Are you also going to leave?" (v 67) Peter replies "to whom would we go" (v. 68) and "we believe, and we know you are the Holy One of God." (v. 69)
At the point Peter is answering for the Disciples there isn't a fire but the Disciples are also, just like Elisha, burning the "past" and following where God is leading. Elisha has left family, and wealth (12 yoke of oxen! v. 19), behind to follow Elijah where God will lead. The Disciples end up following Jesus, where God leads, to the death.
Yes, we have "decided to follow Jesus" (from the hymn "I Have Decided") but have we really left the "old life" behind? Is God asking us to "burn our bridges," as the saying goes, to leave the past behind us and really follow where God is leading? What if we let God "set our hearts on fire" and we did have the revival? What if, like Elisha and the Disciples, we decided - each and every day - "to love God with our whole heart, mind, soul and strength?" (Mark 12:30) What kind of "burning" would we have?!
