The Difference Between Grace and Mercy

Question: What is the difference between grace and mercy?

When I was growing up in church, I used to hear the saying, "Mercy is when you don't get what you deserve, and grace is when you get what you don't deserve." The idea was that mercy is withholding deserved punishment, and grace is an undeserved gift. In recent years, I have heard people say that when you first fail, you need grace, but if you continue to fail, then you need mercy.

Both ideas roughly represent what modern people mean when they say mercy or grace in English. But the Bible was written in Hebrew, Aramaic, and Greek, and so those definitions are not adequate when we read the Bible, although they aren't completely wrong, either.

So before we get simple, we'll have to get a little complicated. Words in all languages change their meaning depending on their context. For example, in English, the word head can refer to a leader, a bathroom on a ship, the froth on beer, a high peninsula, or many other things depending on the context. Grace and mercy in the biblical languages are no different - they have different meanings depending on the context.

Grace in the Old Testament: Grace is the translation of the Hebrew cheyn, meaning favor. Two good examples are "But Noah found grace / favor in the eyes of the Lord" (Gen 6:8) and "God is opposed to the proud, but gives grace / favor to the humble" (Prov 3:34). In these sorts of passages, cheyn refers to God (or people) being favorably disposed to do good things for someone.

Grace in the New Testament: Grace is the translation of the Greek charis. The basic sense of charis is a gift, or the generosity that inspires that gift. So when Paul says, "For by grace you are saved through faith..." (Eph 2:8), we can say that it is by God's sheer generosity that we receive the gift of salvation (for more on charis, see this post).

Mercy in the OT and in the Gospels: Mercy translates the Hebrew chesed (in the OT) and the Greek eleos and oiktirmos (in the NT). Mercy, like compassion, is when we see someone in need and respond with both pity and action. The blind man of Jericho cried out to Jesus for mercy, because he was in great need (Luke 18:38-39). The Samaritan is described as merciful because he helped the injured traveller (Luke 10:37). Giving to the poor is an act of mercy (eleemosune, Matt 6:2-4). When Jesus blessed the merciful (Matt 5:7), he was talking about people who respond with pity and action to those in need.

Mercy in Paul's letters: Paul usually uses mercy in the same way as the Gospels and the OT. But sometimes, Paul uses the word mercy to describe God's forgiveness of our sins (Rom 11:30-32, 1 Tim 1:13). This is closely related to the meaning of mercy in the rest of the Bible. If we see the hungry, showing mercy means feeding them; when God sees sinners, showing mercy means providing forgiveness.

So, what's the simple answer to the question? Grace and mercy are not totally different; both attributes are at work when God saves us. It is mercy because God sees our desperate need and acts out of pity. It is grace because God gives salvation generously. But we need to be careful not to see mercy and grace as only gifts from God. God expects us to give mercy by helping those in need, and to be gracious by being generous with all that we have.

The picture: Noah's Ark, by Peter Spier. One of my sons loved this book. The first page begins "But Noah found grace in the eyes of the Lord," and the last page shows Noah planting a vineyard. One day he asked me if God liked grapes. I said I was sure he did, but why did he ask? He answered, "Because Noah found grapes in the eyes of the Lord."

Overthrowing Dictators

The following is an answer to a question I received by email:

What does... Romans 13:1-7 mean? It seems to conflict with our beliefs in freedom and justice.This is not what I expected because it seems to be saying that rebelling against a dictator is wrong. It's like the American Revolution and like overthrowing Saddam Hussein were sinful. So how do we reconcile this with our beliefs in freedom and justice? - Thanks, L.L.

First, it is important to know that wise and godly Christians today and throughout history have not always agreed on this issue, so we need to be humble and understanding of other people's opinions. For example, during the Revolutionary War, many Christians felt that that they should support the Revolution, but many believed that the Bible would not allow them to rebel against their king.

What did Paul mean when he wrote this passage almost 2000 years ago? At the end of Romans 12, Paul explained how Christians should respond to those who hate or persecute - by doing good and blessing. He naturally moved into the topic of how to respond to the government, which at that time was dictatorial and occasionally persecuted Christians. Paul said that the Christian's response to government injustice was not to take up arms against the government or stop paying taxes. Christians, Paul said, should obey the government as much as possible (compare to Romans 12:18). Of course, Christians should not obey the government if it tells us to disobey God (see Acts 4:18-20, for example).

What did Paul do when he was persecuted? He used the legal system to defend himself, but he never advocated violent overthrow of the government, even when he was persecuted. In fact, even after being unfairly imprisoned repeatedly, he only advised that Christians pray for rulers so that Christians could be free of persecution (1 Timothy 2:1-4). The church throughout history has generally followed this advice - when persecuted by their own government, Christians have rarely used force to resist.

This suggests (at the very least) that it should be a very rare event for Christians to ever rebel against their lawful government, although we should not obey the government if it tells us to do something clearly against God's will. We should try to use legal means to change the government as much as possible. On rare occasions, Christians have decided that they must use violence to overthrow an evil government when it is no longer a legitimate government. Since there is so little Scriptural support for such a practice, Christians should be very cautious before ever taking such an approach.

Your question about Iraq is slightly different. Paul told Christians not to rebel against their own government, but the war in Iraq is one government overthrowing another. The Bible does not give clear guidelines on when one government is justified in going to war against another. Many Christians throughout history have followed the "Just War" guidelines of the theologian Augustine. This answer is already too long, so I won't attempt to fully explain Just War (wikipedia has a good introductory article on it). The basic idea is that governments have an obligation to defend their people and to right wrongs; but governments must have just reasons for going to war and just ways of conducting war. Christians today disagree over whether the war in Iraq qualifies as a just war, and over whether there is such a thing as just war.
