Paul goes on to tell us that the "letters engraved in stone kill"; they are "a ministry of death." God actually gave us the commandments to show us our sin, so that we would turn to Him. It would be nice if everybody recognized the Ten Commandments as a standard of righteousness, but even that would not bring us to God. "Christ died for our sins, once for all, the righteous for the unrighteous, that He might bring us to God" (I Peter 3:18). Only Christ can bring us to God.
There is a great movement today to restore the Ten Commandments to a place of respect in our culture. But many reject them. We can never force people to acknowledge right and wrong. They choose their own way, and their own thinking. They do not recognize any external values, and say, "There are no Absolutes!" That itself is an absolute statement, and a self-contradiction. They are rejecting truth, and you cannot force them to believe it.
But sadly, most Christians think God saved us so we would try to keep the Ten Commandments. I once heard a speaker say, "God knows we can't keep them, but He just wants us to try," as if God derives some perverse pleasure from watching us attempting the impossible, and always failing. God is not sadistic, and He doesn't want us to be stupid. If I always fail, there is a lesson here.
