“your Father knows what you need before you ask him” (Mathew 6:8)
Also, whatever it is that YOU ask in my name, I will do this, in order that the Father may be glorified in connection with the Son. If YOU ask anything in my name, I will do it.
And, then the caveat:
And this is the confidence that we have toward him, that, no matter what it is that we ask according to his will, he hears us.
Tsk, tsk - wasn't God's will.
