"The Law is holy...just, and good...the Law is spiritual. ,,the strength of sin is the Law....the Law was our schoolmaster unto Christ."

[Part of a 15th Century map showing Galatia.]

"Yet in its true use [the Law], it drives the conscience to seek after the promise of God and to look unto Christ. But that you may so do, you need the aid of the Holy Ghost who may say in your heart: It is not the will of God that you should only be terrified and killed, but that when you are brought by the Law to the knowledge of your misery and damnation, you should not despair, but believe in Christ, "who is the end of the Law for righteousness to every one that believeth" (Romans 10:4). Here all laws cease, and heavenly things now begin to appear. Indeed, the Law says, "Thou shalt love the Lord thy God": but that I may be able to do so, or to apprehend Christ, this the Law cannot give. I speak not this that the Law should be despised, neither does Paul so mean. But because he is treating the matter of justification, it was necessary that he should so speak. We cannot speak basely enough of the Law when on this matter. When the conscience is in this conflict she should think of nothing, know nothing, but Christ only and alone." -Martin Luther

Does God's Law, and His grace fit together? Yes and no. God's Law condemns us, for it's the "letter that kills", because we cannot obey the Law. God's grace says, Christ died to save us from this condemnation, and from the "letter that kills". The Law convicts, pushes us, and makes our hearts tight, so that we look for comfort, and that comfort is only found in Jesus Christ. Jesus said, "Come unto Me, all you who are heavy hearted and have heavy burdens, and I will give you rest for your souls." So the law and grace work together in God's perfect purpose of His salvation of His elect, and yet they are opposites at the same time: "The letter killeth", but grace gives life.
