In giving this “new” command, Jesus is not nullifying the Old Testament law (Matthew 5:17). Rather, He is separating the responsibility of the government (to punish evildoers justly) from the responsibility we all have on a personal level before God to love our enemies. We should not seek retribution for personal slights. We are to ignore personal insults (the meaning of “turn the other cheek”). Christians are to be willing to give more of their material goods, time, and labor than required, even if the demands upon us are unjust. We should loan to those who want to borrow, love our enemies, and pray for those who persecute us (verses 43–48). Enforcing “an eye for an eye” is the magistrate’s job; forgiving our enemies is ours. We see this played out today every time a victim stands up in court to publicly forgive a convicted criminal—the forgiveness is personal and real, but the judge still justly demands that the sentence be carried out.
Jesus’ limiting of the “eye for an eye” principle in no way prohibits self-defense or the forceful protection of the innocent from harm. The actions of duly appointed agents of the government, such as police officers and the military, to protect citizens and preserve the peace are not in question. Jesus’ command to turn the other cheek applies to personal relationships, not judicial policy. The principle of “an eye for an eye” is meant as a judicial policy, not as a rule for interpersonal relationships. The believer in Christ is guided by Jesus’ words to forgive. The Christian is radically different from those who follow the natural inclination to respond in kind.
