Jesus said to him, “For sure, I tell you, unless a man is born again, he cannot see the holy nation of God.” Nicodemus said to Him, “How can a man be born when he is old? How can he get into his mother’s body and be born the second time?” [John 3:3-4 (NLV)]
The being “born again” concept in Christianity isn’t an easy one to understand, yet we see it demonstrated whenever we look at a butterfly. Take the monarch, for example; it starts out as a tiny egg that hatches about four days after being laid. That’s its first birth. The caterpillar actually eats its way out of the shell before munching on the leaf where the egg was laid. Over the next ten to fourteen days, it eats and grows, shedding its skin every time it gets too tight. The full-grown caterpillar then spins silk and attaches its hind end to a leaf, hangs upside down and sheds its skin for the fifth and final time. When the new skin forms, it hardens and takes the form of a chrysalis. The monarch’s chrysalis is a beautiful jade green with little specks of gold and looks like a case that could be used to hold a jewel. Over the next ten to fourteen days, the caterpillar undergoes a metamorphosis. During this stage, the DNA that makes wings is switched on and something almost miraculous happens. When the transformation is complete, the chrysalis bursts open and out emerges a full-grown butterfly. It is born again! The new butterfly hangs onto the chrysalis for a bit, drying its wings and getting stronger, before taking flight and becoming the thing of beauty God meant it to be.
The monarch caterpillar looks and acts nothing like the monarch butterfly and it’s hard to believe they are actually the same creature but they are! The DNA sequence of the caterpillar is identical to that of the butterfly it becomes. The caterpillar, however, no longer exists—it has to die to become a butterfly, much as a person’s old self must “die” when he becomes a follower of Jesus. When we’re “born again,” like the butterfly, we have the same DNA of the person we once were and yet we’re an entirely different creature.
Unlike the butterfly, however, the change is internal not external. Moreover, caterpillars have no choice about whether or not they will become butterflies—they just keep eating and growing and shedding and nature takes its course. On the other hand, people do have a choice about whether they will experience their metamorphosis. They can choose to remain wrapped up in the dark chrysalis of unbelief, a hidden jewel than will never reach its potential, or choose to be reborn in Christ. While there is a scientific explanation for the near-miraculous transformation of a caterpillar into a butterfly, science can’t explain the miraculous transformation that occurs when we are reborn, the Holy Spirit comes to live in our hearts, and we become the things of beauty God created us to be.
