"The law of the LORD is perfect, converting the soul: the testimony of the LORD is sure, making wise the simple." -Psalm 19:7
Chances are we all spend a fair amount of time in front of a mirror every morning. It has nothing to do with vanity, at least for some of us. We get our hair into shape, we wash our faces, for the guys we shave and for the ladies there is the face painting, I mean make up. All this would go on until we deem ourselves presentable to the waking world. We need that mirror for without it we wouldn't know if we washed all the soap off our face or if our shirt was out of place. Here is the question, how do we know if we are presentable in the sight of God? It's for this purpose, God has given us His perfect Law so that when we measure ourselves against it, we might be able to see how much we fall short of His standard.
The sinful human tendency is to measure ourselves against other human beings, and in that state we would never see the need for Christ. After all, I may not be perfect, but I am much netter than "fill in the blank". We boast about our self righteousness as if our good deeds can please God. This is the deadening effect of our sin, we are like drowning men in an open sea who instead of admitting our weakness and cry out for help, we brag to one another about how much better we stay afloat than the next guy. In his mercy God gave us His Law, and the point of the law is not to keep it to please God, no sinner is capable of NOT breaking His Law. Instead, it is meant to reflect back to us our sinful state, much like a mirror that reflects our bed hair, and in response we can admit that we are drowning in a sea of His holy wrath and cry out for mercy.
"So then, the law was our guardian until Christ came, in order that we might be justified by faith." -Galatians 3:24
The Ten Commandment is not just some rules for a group of people far away long ago. The moral absolutes revealed in the Commandants transcends all cultures and ages. No one stands righteous in the sight of God and the verdict is already given, when we match our deeds and thoughts against His holy Law. A sinner must be confronted with his or her wretchedness in the light of the commandants so that they can see just how far they fall short of the glory of God. The Law is not done away in the New Testament age as some Christians would suggest, Christ Himself declared that "it is easier for heaven and earth to pass, than one tittle of the law to fail" (Luke 16:17). The Law of God is an integral part of the Christian message.
"Do we then overthrow the law by this faith? By no means! On the contrary, we uphold the law." -Romans 3:31
