Perhaps most of us would think only the remote tribal people in Papua New Guinea will eat human. But in the bible there was an account of human eating human (literaly Israelites cooking Israelites for food). Read 2King 6:24-33.
If you think that you are a spirtual leper with tons of problems in life and that no one on earth would able to help you, then you will have nothing to loose because the solution of your problem is just one step away. Like the lepers in Samaria, all they do is just move forward and they are the first group of people to eat the food left by the enemies. All we need to do is to die to ourselves and just cling on to God, we will experience the breakthrough that no one has experienced before. The magnitude of your problem is directly proportion to the amount of glory you will give to God. The greater the problem, the greater the glory back to God.
Lepers are the rejected generations. They were being pushed outside the city and they were the unclean generations. Yet, God still can use them to bring the breakthrough to the Israelites. Imagine, if they were not willing to take the step, Samaria will not be rescued because no one dare to go out. If God can use a leper, how much more He will use everyone of us to bring about a great breakthrough in lives?
2 King chapter 6 and 7 also tell us not to take prophecy likely. They also tell the consequence of lack of faith and the consequence of rejecting the servant of God. All these lead to death. No joke, guys. Don't play play.
