I thought or pictured being called to walk on a fractured leg. This may not appeal to us as "good news", but in reality it is. God wants to use us even before we 'feel' ready.
I believe Our Lord is calling His body to 'step out' In His purposes for our lives, and as we do, He is going to bring healing and wholeness on route. It's in knowing our vulnerability, that we realise our utter dependence on His ability to work through us- rags and all. Consider the Jars of clay and their fragility.
2 Corinthians 4:7 But we have this treasure in jars of clay to show that this all-surpassing power is from God and not from us.
