As followers of Jesus, we are called to be salt and light – to form communities that are attractive, winning people to Christ through our lives of love and truth. We’re not called to shake a finger at non-believers or to coerce them to be like us. Paul tells us: “What have I to do with judging those outside? Is it not those who are inside that you are to judge? God will judge those outside” (1 Cor. 5:12-13). Our task is to be an embassy of the love of Christ (2 Cor. 5:20). Only when people are won to Christ will they want to live according to Christian principles.
