One of the greatest natural events on Earth is now underway: the migration of the monarch butterfly.

Each fall, millions of these colourful insects set off from their summer breeding grounds in the northeastern U.S. and Canada for a gruelling journey. They travel thousands of miles across North America all the way to Mexico, where they’ll spend the winter.

Many people believe that the monarch butterflies that leave in the fall are the same ones that arrive back in the spring, but this isn’t so. Individual butterflies don’t make the entire round-trip journey. The ones that migrate from the northeastern part of North America in fall will never return.

Rather, their great-great-grandchildren are the ones who will arrive the following spring, as successive generations keep making their way north. The entire annual migration cycle of the monarch takes about four generations.

Perhaps I’m being fanciful, but I can imagine monarch butterflies telling their children of the awesome journey they’ll be undertaking. They may say that they’ll only be able to go part of the way with them, but to keep the faith and keep going.

Maybe they encourage their children to tell successive generations to keep believing in the promise of return. Because eventually, their descendants will see the promise fulfilled.

Aren’t we in a similar situation as believers?

We’re living in a time when we’re awaiting the fulfillment of a promise, the promise of Christ’s return. We’re not sure exactly when Christ will come back to Earth, but He has promised that He will.
