When you ask Christians to divide the Bible into its two
great themes, they’ll post likely say “Old Testament and New Testament”. This works until you ask if there is any
gospel in the Old Testament or Law in the New Testament, they may say
“NO!” Well, starting in Genesis, we see
the two great themes of Law and Gospel introduced. Law and Gospel is the method that the great
reformers of the Sixteenth Century came to understand the proper way to read
and understand the Bible. This is also
seen in St. Paul’s letter to the
Church in Rome, as well as
throughout the Old and New Testaments.
What is Law
Most Christians would say that the Law is the 10
Commandments or the Law of Moses. While
that is correct, it is only part of the Law. The Law is want God has commanded us to do and not to do. While we benefit from a written Law, God’s
Law existed prior to Moses. Just read
Genesis and the story of Cain and Able. While Cain knew that murder was wrong, it was not written on a stone
tablet for everyone to read (Genesis 4). Another example is Joseph. How
did he know adultery with Potiphar’s wife was a sin when she tried to seduce
him? (Genesis 39:9)
Paul wrote that the Law of God has been revealed in His
creation so that we are all without excuse. (Roman 1:20). Claiming to
not know God’s law is like telling the policing officer that you never saw the
posted speed limit sign, as he writes you a ticket of going 60 in a 40.
Jesus was also a law giver. In the Sermon on the Mount, Jesus teaches us that it is not just our
actions, but our thoughts and intentions that break the Law. If I am angry with another, it is the same as
murdering them in God’s judgment. Jesus
did not come to abolish the Law or the Prophets, but to fulfill them (Matthew
4).
With God’s Law, God demand perfect obedience. Anything less is unacceptable to a holy and
righteous God. (Galatians 3:10). God
doesn’t grade on the curve or give partial credit for our attempt to following
the Law.
What is Gospel
Most Christians would say that the Gospel is either the
first four books on the New Testament (Matthew, Mark, Luke and John) or Jesus
dieing for the sins of the world. Again,
that is part of the answer. The Gospel
is God doing for man what man cannot do to fulfill the Law. In Genesis 1, God gives His creation man as a
gift. Adam did not earn this gift. After Adam and Eve broke God’s Law, God shows
his love by providing for Adam and Eve. This love is shown by God’s promise of Christ and the punishment of
Satin (Genesis 3:15) as well as
providing clothing for them (Genesis 3:21). Even after their rebellion, Adam and Eve
still received God’s blessing through children.
Through Genesis, God shows us the gospel with Noah, Abraham, Lot, Jacob, Joseph and the rest of Jacob’s family. The history of Israel shows us the gospel in God redeeming Israel despite their consist sin. The gospel, as
shown in the Old Testament, points to Christ.
The Gospel is God’s gift to us. Through the Old Testament, God’s grace was
always free, just as it is in the New Testament and now. There is nothing we can do to merit what God
gives us. St. Paul stated this best in Romans 3:22-24:
“This righteousness from God comes
through faith in Jesus Christ to all who believe. There is no difference, for all have sinned
and fall short of the glory of God, and are justified freely by his grace
through the redemption that came by Christ Jesus.”
Throughout the New Testament, the gospel does not come to
those who obey the Law, but those who realize that they cannot and must rely on
Christ.
What does this mean?
When we understand Law and Gospel, we then can truly
comprehend how sinful we really are and how great the salvation that God gives
us through Christ’s sacrifice. If we
fail to understand the proper distinction between Law and Gospel, we can
confuse how we are saved and how to live the Christian life.
Martin Luther coined the phrase “Theologian of Glory” and
“Theologian of the Cross” to help explain this confusion. The Theologian of Glory, or those who believe
and teach this belief, focus on what we do to please God through our actions
while the Theologian of the Cross focus on what Christ did for us on the Cross
since we cannot do anything to please God.
Jesus gave us the best example of the two theologians in his
parable of the Pharisee and the tax collector. While the Pharisee prayed on how righteous he was, the tax collector
said “God, have mercy on me, a sinner”. Jesus stated the tax collector, not the Pharisee, was justified before
God. (Luke 18:9-14).
