Dying to self is not an abstract spiritual experience.  It is what you do practically day by day in the circumstances and relationships of your life.  Even our spiritual experiences are tested and proven in these two arenas.  The call heard and answered is a call to be lived.  The surrender at His cross must be lived out on our cross.  The journey across this wilderness is never a walk in the park. 

“If anyone wishes to come after Me, he must deny himself, and take up his cross daily and follow Me. “For whoever wishes to save his life will lose it, but whoever loses his life for My sake, he is the one who will save it.” Luke 9:23-24 (NASB)
