Psalm 119:176 I have strayed like a lost sheep. Seek your servant, for I have not forgotten your commands.
It does not matter that you have refused to help out before, or that you have been shy in coming forward in the past – now is the time – now is right!
God is not going to turn you away because you have not done something before, and He is not going to turn you away because of what you have done in your past.
Turn to Him, offer you help and wait for Him to call you forward and fulfil your role He has already designed for you!
