Why doesn’t Nathan simply rebuke David on the spot? Why the long story and the strategic side-tackle?

It’s because before confronting ourselves, we need to undo our self-righteousness.

We each have a nearly impenetrable fortress of resistance when we’re called out on our wrongs. It keeps us blind to our blindness.

The way that God punches through David’s self-deception is one of the most lauded turns of literary brilliance in written history. Nathan doesn’t simply accuse David. Nathan peels back David’s self-righteousness by turning his rules against him. David is knocked over by the weight of his own standards. The very mechanism by which David has condemned the guilty to cover his guilt is turned on himself. His excuses have become his own liability, like a sword with a blade on both ends. It’s what Jesus meant when he said, “For in the same way you judge others, you will be judged, and with the measure you use, it will be measured to you.”  

David required a brutally honest confrontation, but it would take more than a lesson in theology or a list of sins. No one changes that way.

God rebukes David by first removing any possibility of an excuse or objection.
God revokes David’s self-righteous capacity to absolve his own sin.
David needed to confront himself, before the sight of God, without the slimmest avenue of escape or deflection.

If you want any hope of change, freedom, progress, recovery, and growth: you’ll need to confront yourself, too. It’ll be the most painful thing you’ve ever done, because we’re so used to protecting our fragile, brittle egos. But it’s more painful to stay stuck in the lie.

If you’ve ever tried to confront your friend about their thing, you were amazed at their automatic defenses and sudden snarling. I’m sometimes surprised by my own excuses, too. When I’m guilty, I attack. It’s the perfect way to get out of accountability. When someone does something wrong, it’s all their fault, but when I do something wrong, it’s my environment or my family or my stress. When we get caught red-handed, we go into a monologue of rehearsed responses that we almost really believe, because it took so many steps of rationalizations to get there.

When you want to escape by saying, “Well-what-about-them?” — God will twist you around to say, “Well-what-about-me?” The only thing that will destroy hypocrisy is humility. Part of humility is to quit holding up a mirror at others and to use it on myself first.

For the first time in a long time, David is being honest with himself before God. He lets the truth undress him. There’s no place for him to run. His own judgment has betrayed him, and this is how God will work on us, too. He will dislocate your blame, one excuse at a time, until you really take a look at yourself and see you as you really are.
