By 1 Timothy 1:8-11
Now we know that the law is good, if one uses it lawfully, understanding this, that the law is not laid down for the just but for the lawless and disobedient, for the ungodly and sinners, for the unholy and profane, for those who strike their fathers and mothers, for murderers, the sexually immoral, men who practice homosexuality, enslavers, liars, perjurers, and whatever else is contrary to sound doctrine, in accordance with the gospel of the glory of the blessed God with which I have been entrusted.
“The law of the Lord is perfect converting the soul.” (Psalm 19:7 NKJV)
We have spent quite a bit of time talking about the purpose of the law when we were going through Romans. We are reminded here that the law is good if one uses it lawfully. What would a lawful use of the law? Well, Psalm 19 tells us that it is lawful in converting the soul. Remember that the law is our schoolmaster that brings us to Christ. You and I must be condemned under the weight of the law before we will cry out for deliverance from it’s burden upon us on account of our sin.
Removing the 10 commandments from government buildings is detrimental to our children and our society in general; let alone their eternal destinies. The 10 commandments are to be laid down in general so that people can know of their sin. When you have an entire school building full of children (who desperately need the foolish driven from their hearts) and no eternal accountable law displayed; you have, I guess, a culture like we have today.
When you and I encounter the common sins of our culture displayed before us as if they were good, we need the boldness and humility to share the law of the Lord. After all, what else converts the soul?
