The connecting word **If** introduces a hypothetical conditional relationship. If you believe in Jesus and confess what he has done for you, then you are a Christ follower. (See: [[rc://en/ta/man/translate/grammar-connect-condition-hypothetical]])
**Light** here refers to God’s holiness and goodness. This could be translated as: “righteous rule over people, which is like light.” The Bible often compares evil to darkness, and goodness to light.
