Are you qualified for God to use you?

A lady came for prayer but was nervous about trusting anyone, having had a terrible history of abuse by people she thought she could trust.
To reassure her about my suitability to pray with people in vulnerable situations, I laid out my credentials.
I have all seven of the deadly sins.
I have probably every psychological problem in the book.
I have done just about everything wrong that you can think of.
I am not unshockable; hearing about evil is always a terrible shock to me.
I am not, although I have been offered opportunities to train as such, a spiritual director, psychologist or counsellor, either Christian or secular.
I am no good at all at resolving my own problems and have to run to God for help with every crisis, major or minor.
I am not a hundred percent trustworthy, because no human being is, and in fact I have trouble trusting myself, let alone expecting anyone else to.
And yet, God uses me. I'm not sure why or how, but sometimes he works through me to heal people. Sometimes he works around me. And sometimes he works despite me and my misdirected efforts to tell him what to do. And uses even my failures to lead to something good.
So if this poor young courageous wounded and hurting soul was willing to take the risk of allowing someone so ill-equipped and unqualified to pray for Jesus to help her now, I was willing to do it.
She was willing, and went home feeling at peace, thanks to Jesus who used her bravery and even her vulnerability to accomplish what she couldn't achieve on her own.
He doesn't need us to be in a usable state, to use us for good. He just needs us to say yes, and let him do what only he can do.
