Question: "What is the law of Christ?"
Answer: Galatians 6:2 states, “Carry each other’s burdens, and in this way you will fulfill the law of Christ” (emphasis added). What exactly is the law of Christ, and how is it fulfilled by carrying each other’s burdens? While the law of Christ is also mentioned in 1 Corinthians 9:21, the Bible nowhere specifically defines what precisely is the law of Christ. However, most Bible teachers understand the law of Christ to be what Christ stated were the greatest commandments in Mark 12:28–31, “‘Which commandment is the most important of all?’ Jesus answered, ‘The most important is, “Hear, O Israel: The Lord our God, the Lord is one. And you shall love the Lord your God with all your heart and with all your soul and with all your mind and with all your strength.” The second is this: “You shall love your neighbor as yourself.” There is no other commandment greater than these.’”
The law of Christ, then, is to love God with all of our being and to love our neighbors as we love ourselves. In Mark 12:32–33, the scribe who asked Jesus the question responds with, “To love him with all your heart, with all your understanding and with all your strength, and to love your neighbor as yourself is more important than all burnt offerings and sacrifices.” In this, Jesus and the scribe agreed that those two commands are the core of the entire Old Testament Law. All of the Old Testament Law can be placed in the category of “loving God” or “loving your neighbor.”
Various New Testament scriptures state that Jesus fulfilled the Old Testament Law, bringing it to completion and conclusion (Romans 10:4; Galatians 3:23–25; Ephesians 2:15). In place of the Old Testament Law, Christians are to obey the law of Christ. Rather than trying to remember the over 600 individual commandments in the Old Testament Law, Christians are simply to focus on loving God and loving others. If Christians would truly and wholeheartedly obey those two commands, we would be fulfilling everything that God requires of us.
Christ freed us from the bondage of the hundreds of commands in the Old Testament Law and instead calls on us to love. First John 4:7–8 declares, “Beloved, let us love one another, for love is from God, and whoever loves has been born of God and knows God. Anyone who does not love does not know God, because God is love.” First John 5:3 continues, “This is love for God: to obey His commands. And His commands are not burdensome.”
Some use the fact that we are not under the Old Testament Law as an excuse to sin. The apostle Paul addresses this very issue in Romans. “What then? Are we to sin because we are not under law but under grace? By no means!” (Romans 6:15). For the follower of Christ, the avoidance of sin is to be accomplished out of love for God and love for others. Love is to be our motivation. When we recognize the value of Jesus’ sacrifice on our behalf, our response is to be love, gratitude, and obedience. When we understand the sacrifice Jesus made for us and others, our response is to be to follow His example in expressing love to others. Our motivation for overcoming sin should be love, not a desire to legalistically obey a series of commandments. We are to obey the law of Christ because we love Him, not so that we can check off a list of commands that we successfully obeyed.
