How should I respond in this situation to glorify God? Do it. Repentance and faith lead to concrete changes in behavior, emotion, thoughts. Righteousness is just as specific as the sins described in question #2. At the simplest level, I may simply take a deep breath and relax, trusting that God is indeed in control. But God has other fruits in mind, too. I become a charitable, courteous driver. What does it matter if I’m two more car lengths behind? I’ll let a couple of cars in. God has set me free of both the hostile and competitive aspects of sinful anger. The traffic jam is no longer a dog-eat-dog battle. I offer thanks to God. I plan what I will say to the person I’ve stood up: not anxious excuse-making or blustering irritation, but the simple facts, an apology, and a concern for his welfare.
