How do we use the law?

“The law is good if a man use it lawfully.” (1Timothy 1:8)

Timothy is a pastor of one of the churches. Paul the apostle is concerned that true doctrine be taught and speaks of “charity, out of a pure heart, and of good conscience and of faith unfeigned.”  (l Timothy 1:8) and then he says the law is good if used correctly.  May it ever be so with each of us.
