The gospel and law work in tandem, bringing people to Jesus (and ultimately salvation) and helping Christian ambassadors bring about a more just society. We need to abandon the justice vs. gospel extremes. Our focus as Christians is not “We just need to preach the gospel.” It’s also not “Social justice is the gospel.” Instead, we partner with Jesus to preach the gospel, make disciples, and teach them to obey biblical principles in all areas of life.
There are two misunderstandings about justice that have led to confusion in the Christian community.
First, there’s often not a clear distinction between the law of God and his gospel, especially in discussions related to justice. These two aren’t the same thing. The gospel literally means “good news.” It’s the good news that “while we were enemies we were reconciled to God through the death of His Son” (Romans 5:10). The gospel is good news when we understand that we do not and cannot earn our salvation. The work of redemption and justification has been finished by Christ, on the cross, at Calvary.
The gospel is not the law. Many Christians misunderstand the law. Some think that when Jesus died on the cross, he did away with all our moral obligations. This not the case.
Remember, the law of God gives us our moral standard in life, including the standard of justice. Of course, Jesus is the only man who ever lived up to that standard, but—with God’s help—we still need to pursue a holy life. Peter said, “Be holy yourselves also in all your behavior.” He then quoted the Law: “Because it is written, ‘You shall be holy, for I am holy’” (1 Peter 1:15–16).
Think about what Jesus said in Matthew 22. A lawyer asked, “Teacher, which is the great commandment in the Law?” Notice the question is about law, not the gospel. This is really important. Jesus answered, “‘You shall love the Lord your God with all your heart, and with all your soul, and with all your mind.’ This is the great and foremost commandment. The second is like it, ‘You shall love your neighbor as yourself.’” Now listen to his summary statement: “On these two commandments depend the whole Law and the Prophets.” Christians miss this here. Notice our obligation to love is not the gospel. Loving God and loving your neighbor is law.
Here’s why I bring this up: The gospel is about God’s love for us. It’s his rescue plan for sinners. The law is about our love for God and others.
