"We must go vertical in our quest for new ground as Christians"

The conquering of Jericho is a powerful example of GOD'S words in Isaiah 55:8-9:
"For my thoughts are not your thoughts, neither are your ways my ways, saith the LORD.  For as the heavens are higher than the earth, so are my ways higher than your ways, and my thoughts than your thoughts."

Jericho was an imposing city, built on a hill and ringed not just with one wall but two, the outer being 6' thick, and the inner 12'.  Timbers were laid across these walls supporting houses, one of which was Rahab's, the harlot turned helper.
To suggest this city be destroyed and taken by merely marching around it was beyond unorthodox, it was ludicrous to any rational military strategist!  What would normally take months or even years to win by besiege in the plan of men would be accomplished GOD'S way in one week without firing a shot.  Joshua would need to forget the victories East of the Jordon and trust GOD to a new level at Jericho.

It is said that common sense is very uncommon.  However, I would take issue with that, observing that common sense is not only common, it is ubiquitous.  While to be expected of the worldling, common sense is cancerous in the church and the enemy of THE SPIRIT OF GOD. 

Failures occur when we fail to stay the course.  Too often we deify common sense and neglect to show up after a couple of days compassing the ground GOD wants us to gain in our Christian life.  Hang in there with those who lead spiritually.  See it through to its miraculous conclusion walking in the SPIRIT, not the flesh.

Great spiritual victories are not won on the horizontal.  We must go vertical in our quest for new ground as Christians launching all on the SPIRIT.  Leap to your knees and watch GOD bring down the walls which stand in your way.
