Again, it’s not complicated. There are volumes that describe our life of faith, yet here Jesus simply says that we are salt and light, proclaiming the good news in the way we live.
Think of salt as that which provides flavor, brings healing, fights corruption, preserves, and creates thirst. And then think of light, that which floods in and illuminates the dark. Jesus is telling us that when we follow Him, our lives of faith offer flavor, lead to healing, preserve the spirit of others, and provide light in an otherwise dark, hopeless world.
In such situations a friend may say, “Your love for Christ is contagious,” or “I’ve learned God’s truth from you. It’s guiding my life,” or “Your life of faith shines bright in the dark hole I’m in.” These metaphors of salt and light indicate the powerful Christian influence we can have on hurting, searching souls around us. Our message is fresh, positive, exciting, constructive, and full of life.
When the reality of Christ can be seen in our lives, our Heavenly Father is honored.
