There are essentially four ways you can spend your life. You can waste it in Egypt by living for worldly pleasure and material success (all of which are temporal and fleeting). You can waste it in Babylon by living for the growth and success of organized religion. You can waste it in the wilderness by living your life in transition. Or you can spend it on Jesus Christ in a building site in Jerusalem. So where are you living today? Egypt? Babylon? The wilderness?
