IT IS NATURAL AND NORMAL TO FEAR REJECTION. 
THE ONLY THING WRONG WITH IT IS IF YOU ALLOW
THE FEAR TO DOMINATE YOU SO THAT IT HOLD YOU
BACK FROM FUFILLING YOUR POTENTIAL IN YOUR 
CALLING FROM GOD.

1 John 4:17-18King James Version (KJV)

17 Herein is our love made perfect, that we may have boldness in the day of judgment: because as he is, so are we in this world.

18 There is no fear in love; but perfect love casteth out fear: because fear hath torment. He that feareth is not made perfect in love.
