At first read this verse is a warning and instruction on how to live my life.  It tells me that to not serve Yehovah is to doom myself.  History proves that Our Creator requires two things primarily #1 Love Him with all our heart #2 Remain obedient to His commands.  I guess what I need to apply from this verse is that if I truly love Yehovah wouldn't I easily put aside self indulgence in order to become a Holy Temple for Him in which to dwell?  When I release my fear, it testifies that Yehovah has never wronged me in anyway...
