Law and Gospel: Part 10 : The Relevance of the Moral Laws of God in the 21st Century

Over the last couple of posts, we have looked at the three different types of Law found in the Old Testament and I made the point that, while some aspects of specific Old Testament commands are not applicable to contemporary Christians, that God’s moral law (summarized in the ten commandments and the great commandments of Christ) is eternal, unchanging, and written upon the heart of mankind.

That all may be so, but in what way do the law and gospel relate to current Christian living? My answer, and the answer we give our children, is that the ten commandments provide a rule for living, or, put another way, they give specific instruction regarding how a Gospel people should live. In other words, they serve the same function in the 21st Century as they did at Sinai: they answer the question, "How should God’s people live?".

We believe and confess that salvation is sola fide, by faith alone, but it is not a faith that is alone. James 2:11 and even Jesus’ summary words of the Sermon on the Mount (Matt. 7:24-27) preclude the possibility of a true believer making an empty confession. Our works still matter, not that they affect our standing before God, nor that by them we accrue favour, but because they demonstrate our faith.

But, how can we know if our works are rightly honouring to God and "worthy of the calling wherewith we were called"? Even living in light of the Gospel, is there not a rule of living given by God? Or, should each man be led independantly by the Holy Spirit into right living? There are those who claim that, because of the leading of the Holy Spirit, there are no standards of conduct for Christians, save the standard of "yielding to the Spirit. While not denying the work of the Spirit in each Christian’s life, I believe that this view only gives have the Biblical truth.

We believe that God has graciously revealed His mind on these matters. God has given specific commands, even to His New Testament people. Think of the specific commands of Christ. Think of the beginning of John’s ministry ("Repent! For the Kingdom of Heaven is at hand!"). Think of the fuller understanding of the ten commandments laid out by Christ in Matthew 5-7. None of these statements make sense if there is not a transcendant, objective and revealed standard of conduct and life for the people of God. The idea of obedience is meaningless if there are no commands to which we should be obedient. The idea of repenting makes no sense if there is no rule of conduct that we have failed to keep.

I’ll conclude by saying, both "law" and "gospel" make demands, both offer promises and both are bathed in the grace of God. In many ways, the distinction between law and gospel is a false one: Law without a gospel is hopeless and condemning, a gospel without law is rudderless. The essential issue is how we respond to the demands and promises of God’s Word. May our gracious God help us live obediently to the praise of His glorious name.
