It's not the one thing I would do for him it's the one thing am doing and will do for him and that is to be whatever it is he needs.
One thing I always let him know is that it I am not any one thing for him I not a servant nor a prince I am not a teacher nor a prophet I do not walk in any one of the spiritual gifts or realm I can be and will be whatever it is he desires even if it isn't in my normal range of gifts.
I am and will be his wonder card
