Serving the Lord with fear.

Psalm 2:11
Serve the Lord with fear and rejoice with trembling.

What do we define as fear?  Well that answer would have to
be something or someone we are frightened off.  fear can also mean that it is something in which we do not understand or know
about.  Ignorance can bring on fear because we don't understand.  To fear God is entirely different, the meaning of fear here is to respect Him, and to want to obey Him.  It is a desire to those of
us who have accepted God in our lives.  To serve God in fear is to
respect him, and to follow him, also to obey him with all our being.
