Let's say that one day you accidentally rip the only decent pair of jeans you own. So you decide to head to the mall to pay a visit to the Gap to buy a new pair. Let's say you enter the mall same as you always do but are immediately approached by a friend who asks if he can borrow $5 for some lunch over at the food court. No sooner do you slip your friend the money and you turn around to discover an old high school classmate staring at you, asking you if you can forgive her for that time she turned you down for a date years ago (and was kind of cruel about it at that). You say, "Sure, I guess so," but no sooner are those words out of your mouth and another acquaintance of yours is in front of you, asking for your advice as to whether or not he should accept the promotion being offered to him at work. And then let's say that this goes on for quite a while with one friend after the next standing in front of you requesting this or that. Finally, after this goes on for an hour or two, you look up to discover that there is now a line of people running the length of the mall, all waiting to ask you for something.
Recently I heard about a videotape that someone made to illustrate what it might be like to be God. The tape runs for just over an hour and it features nothing but one person after the next making a request, asking for advice, seeking direction, requesting money, and so on. Face after face after face appears on the screen, each in a plaintive mode of asking for something. It's curious that Jesus more than once illustrates prayer with images of exasperation. In Luke 11 we have a friend at midnight baying for bread from someone already tucked cozily into bed. A few chapters farther on in Luke we find the parable of the unjust judge who finally gives in to the persistent widow not for any noble reason but just to get her off his back.
It has always struck me as odd that Jesus would use these somewhat negative images to talk about prayer. Surely we don't want to think of God as being exasperated but maybe just maybe Jesus, as the Son of God, knew what it was like to be barraged day and night by an endless line of people asking for advice, money, direction, or whatever! None of us would last very long if my scenario in the mall ever really happened. It is a credit to the almighty power of God that he is able to handle the simultaneous prayers of millions, if not billions, of people all the time.
