To be transformed is to be irrevocably changed. Once a caterpillar becomes a butterfly, it can no longer be a caterpillar again. Butterflies never return to being caterpillars, nor do those saved by the cross of Jesus go back to a life ruled by sin.

The end of Romans 5 says that where sin increases, so does grace. To the sinful mind, this sounds like an invitation to sin more to get more grace. In Romans 6, Paul responds by teaching what it means to be transformed. Yes, more sin equals more grace, but the response by one transformed by the gospel is not to desire more sin but more righteousness.

When the angel revealed to Joseph that Mary was pregnant with the Messiah, he was declaring that the long wait was over. The long-anticipated Messiah was coming. The Christ has arrived.

The name that the prophet Isaiah gives the messiah is Immanuel. As Matthew recounts the encounter Joseph had with the angel, he reminds us that this name means “God with us.” God stepped out of the glory of heaven to dwell among and with us.

The prophets sang, “Oh come, oh come Immanuel.” The angel declared to Joseph Immanuel had come. Through Jesus, we know the amazing love of God's presence, and sacrifice. And through the love of Jesus, we are transformed.

Using the example of the lamp I want you to see to fundamental truths about following Christ. When you believe in faith on Jesus for salvation you are forever changed – you are irreversibly transformed. The humble oil lamp demonstrates two ways this transformation changes you - transformed nature and transformed obligation.
