The door is already locked, and my children and I are in bed. I can’t get up and give you anything.’ I tell you, even though he will not get up and give you the bread because of friendship, yet because of your shameless audacity he will surely get up and give you as much as you need. “So I say to you: Ask and it will be given to you; seek and you will find; knock and the door will be opened to you.
