Asking is polar co-operation. Jesus turned the fact to a use exactly the contrary of its deistic sense. He made the all-knowing Fatherhood the ground of true prayer. We do not ask as beggars but as children. Love loves to be told what it knows already.
Every lover knows that.
It wants to be asked for what it longs to give. Dr. Buswell uses a different illustration, but it makes the point beautifully. Parents know that theoretically it would be possible to provide for one's children in an impersonal and distant way. You could provide meals prepared ahead of time that they could take from the freezer, leave money for them to buy what they want, have servants to take care of laundry and so on. They would never have to ask you for anything.
