Today is a day to work out these thoughts with God. Simply pray all day. Ask God to take your limitations and bless your work. Pray for specific limitations you struggle with and those that you don't even realize. Pray that through service and knowing God better that you will become more aware and trusting of Gods' unlimited power.
As always, this is for your benefit and relationship with God, so be honest and if necessary, confrontational with yourself, especially where it's difficult.
