7 What shall we say, then? Is the law sinful? Certainly not! Nevertheless, I would not have known what sin was had it not been for the law. For I would not have known what coveting really was if the law had not said, “You shall not covet.” 8 But sin, seizing the opportunity afforded by the commandment, produced in me every kind of coveting. For apart from the law, sin was dead. 9 Once I was alive apart from the law; but when the commandment came, sin sprang to life and I died. 10 I found that the very commandment that was intended to bring life actually brought death. 11 For sin, seizing the opportunity afforded by the commandment, deceived me, and through the commandment put me to death. 12 So then, the law is holy, and the commandment is holy, righteous and good.
13 Did that which is good, then, become death to me? By no means! Nevertheless, in order that sin might be recognized as sin, it used what is good to bring about my death, so that through the commandment sin might become utterly sinful.
-Romans 7:7-13
When you’re injured, your body experiences pain as a means to tell you something is wrong. The purpose of the law is to help you do that with your soul. Our souls are vehemently sinful, but it can stay pretty well hidden. But when we are confronted by a law, especially God’s law, our sinfulness comes light. No matter the rule or law, our soul just wants to disobey. I see that in baby Taylor. Baby Taylor always wants to crawl to the places that we’ve set as off-limits. Sometimes she’ll even look at us to make sure we’re watching her blatantly disobeying us. It’s not fun disobeying if the people you are disobeying don’t know! We’re all like baby Taylor. There’s something in us that just wars against authority and anything that’s godly. That’s our sin nature that the law brings out in us.
So we need God’s laws and rules because not only do they tell us how to live life to the full, they show us how messed up we are on the inside. We just can’t follow them. It’s like there’s something wrong with us, because there is! It’s sin!
This is why the Apostle Paul says that the law is good. God’s laws and rules show us how we’re messed up and compel us to seek help. If we don’t know we’re messed up, why would we ever come to God for help? Only a sick man seeks a doctor. Only a sinner seeks a savior.
