Tropism

Do you remember learning about "tropism" in the plant section of your 4th grade science book? You know, phototropism, hydrotropism, and thigmotropism? I remember being intrigued and looking for examples of tropisms in the plants around me.

The Biology Online dictionary defines "tropism" as "A movement or growth response of a cell or an organism to a stimulus, which may either be positive or negative depending on the source and kind of stimulation." The entry goes on to differentiate "tropism" from similar phenomena such as "kinesis" or "taxis" and then offers examples of various kinds of "tropism."

You wanted to know all of that, right? (But really, it's pretty cool.)

Over the years, the idea of tropism has grown deeper roots in my life. According to the Bible, the God who made the world, crafts each human individually, and orders every day with personal attention and care is continually calling people to come to Him and to know Him. He's always pursuing relationship with people. There's a very real sense in which He intends for every single facet of your life in every single stage of your life to act as a stimulus in your relationship with Him. The Christian's interaction with life should be "theotropic."

That being said, I wanted to share two tropism parables with you.

1). Thigmotropism (response to touch stimuli).

I wrote this little poem-prayer back when I was in school (and when I thought that writing poetry in Elizabethan English was a thing. I've since learned differently. Don't judge.).

Thigmotropy

As vining plant, when touched by stick,

In glad dependence graspeth quick,

Let me, dear Lord, when touched by Thee,

Display a like thigmotropy.

2). Heliotropism (response to the sun).

When I took a walk a few evenings ago, I noticed these field clovers craning their necks west, turning full face toward the setting sun. The responsiveness of the plants to the sun echoed in my own heart as a prayer for myself and the people I love: "May our hearts always turn toward You like that."

What have you seen recently that has helped your heart grow toward God?
