The majority of the time spent in the wilderness for the Israelites was in disobedience.  Numbers 21 gives the story of venomous snakes biting the Israelites, and the only way for deliverance was to simply look at a replica snake on a pole.  The same is true for us.  Christ became a curse for us, and all we need to do is look to the cross at Calvary for deliverance.  Pastor Jeff will talk more about this in a message called "Call On The Lord And Live."
