Does the “eye for an eye” rule apply to Christians?

No, this rule is not binding on Christians. It was part of the Mosaic Law, which Jesus’ sacrificial death abolished. —Romans 10:4.Even so, the rule provides insight into God’s way of thinking. For example, it shows that God values justice. (Psalm 89:14) It also reveals his standard of justice —namely, that wrongdoers should be disciplined “to the proper degree.” —Jeremiah 30:11.
