Jesus said we are "salt and light." This text teaches us to "be who we are." We don't have to try and be salt and light, we already are. We need to make sure our lives create a thirst for Jesus and find ways to shine the light within us. Someone has accurately stated "we are like the moon and Jesus like the sun. We have no real light of our own, we simply reflect the light of Jesus." So, shine your light - intentionally do good works, not to call attention to yourself but to glorify Jesus.
