In the analogy of light to the world, the good works of Christ’s followers are to shine for all to see. The following verses in Matthew 5 highlight this truth: “You are the light of the world. A city set on a hill cannot be hidden; nor does anyone light a lamp and put it under a basket, but on the lampstand, and it gives light to all who are in the house. Let your light shine before men in such a way that they may see your good works, and glorify your Father who is in heaven” (Matthew 5:14-16, NASB). The idea here is similar—the presence of light in darkness is something that is unmistakable. The presence of Christians in the world must be like a light in the darkness, not only in the sense that the truth of God’s Word brings light to the darkened hearts of sinful man (John 1:1-10), but also in the sense that our good deeds must be evident for all to see. And indeed, our deeds will be evident if they are performed in accordance with the other principles that Jesus mentions in this passage, such as the Beatitudes in Matthew 5:3-11. Notice especially that the concern is not that Christians would stand out for their own sake, but that those who looked on might “glorify your Father who is in heaven” (v. 16, KJV).
