So now I am giving you a new commandment: Love each other. Just as I have loved you, you should love each other. Your love for one another will prove to the world that you are my disciples. [John 13:34-35 (NLT)]
We recently visited a botanic garden that boasts a butterfly conservatory inhabited by a spectacular collection of tropical butterflies. There I was introduced to the shiny Blue Morpho. God outdid Himself with these enormous beauties so showy that pilots report seeing them from the air as they fly over the rainforest. When Adam and Eve were banished from Eden, I’m thankful God didn’t make them leave the butterflies behind.
Hoping to get a photo of one of these spectacular creatures that were flitting about, I searched through the conservatory for one that was still. Although the Morpho’s upper wings are a vivid blue color, their undersides are a dull brown. When its wings were folded, I mistook the Morpho for another large brown butterfly: the giant owl. It was only when it spread its wings in the sun’s light that I recognized the Morpho by its vibrant blue color.
As Christians, we are called to love and, just as its blue iridescence identifies the Blue Morpho, our love identifies us as Jesus’s disciples. But, if we just sit in the shade and never move out in the world, we’ll look like everyone else. Wings are meant to be spread and Christian love is meant to be shared. If pilots can spot a butterfly from the air, people should be able to see evidence of a Christian’s love wherever we are!
What I later learned is that while the dreary colors of these butterflies’ undersides are produced by pigments that absorb and reflect light, the brilliant blue of their upper wings has nothing to do with pigment. That color comes from the way light reflects off transparent microscopic scales on their upper wings. There’s an involved scientific explanation but (in layman’s terms), when light hits ridges on those scales, something called “constructive interference” happens which cancels out certain wavelengths of light. As a result, when light hits the upper wings of the Blue Morpho, our eyes perceive them as being a shimmering blue.
Looking at my pictures, it’s difficult to comprehend that the Blue Morpho’s dazzling iridescence isn’t real. The blue is merely an optical illusion resulting from the architecture and arrangement of transparent scales on its brown wings. I guess we could call it a fake since it doesn’t show us its true colors. It’s a little like the Pharisees: those men Jesus criticized because they did everything for show. Their faith and righteous were but an illusion because their hearts were filled with hypocrisy and evil. Unlike either Blue Morphos or Pharisees, however, there should be nothing illusory or deceptive about a Christian’s love; we are expected to be true blue to Jesus and His command to love one another.
