Ready At ALL Times!

How are we supposed to prepare at all times? How are we to live our days and how important is prayer?  What should we pray for? Are we ready if Christ were to come back tomorrow?  Are we worthy enough? Is God our first priority and can we trust Him to take care of ANY situation that we are faced with? Do we truly understand how important God is in our lives and if we shut Him out, what would the consequences be?
