Leviticus 14 describes the elaborate rituals under the Law of Moses for ritually cleansing lepers and houses. Complicated procedures involving various sacrifices. Massive contrast to the freedom and grace we have through Christ. “By works of the law no one shall be justified” says Paul.
We are justified through our faith, demonstrated in our lives. We live that way because of “the Son of God, who loved [us] and gave himself for [us].” We have been set free from the slavery of rituals that offer nothing but condemnation, so that we can live a life of “faith working through love.” So lets stand fast, and “not grow weary of doing good”, knowing that in due season we can reap the reward of eternal life.
