Confidence vs Fear

So I was visiting with a co-worker today about a book that we are reading, A Confident Heart, by Renee Swope.  We were talking about opportunities that we may not pursue because of our lack of confidence either in OUR abilities or HIS availabilities.  I don't think of myself as a fearful person.  I would even say that I am a pretty confident person, but I do know that I have missed out on many experiences because of my lack of initiation just because I don't think I deserve it.  It is negotiable for me.  I can have it or live without it - no big deal.  I see now, that I do hold myself back because of non-confidence. (Is that a word?)  I believe I can perform any tasks, with confidence, that I am asked to tackle, but do I chase possibilities?  What am I afraid of?  We referenced Jeremiah 17:7 "But blessed are those who trust in the Lord and have made the Lord their hope and confidence."  Although I say this is true, how much confidence am I putting in the Lord and what his will is for me?  Funny thing - none of the scriptures I read ended with - "if it is Your will."  Just straight up - "...You won't be disappointed." "I am doing a new thing..." "All things work for the good..."  "All things are possible..."  I am so thankful for a God that has confidence in me when I have tremendous doubt or even a shadow of doubt.
