Science writer Hope Jahren shares an interesting fact about plants, especially how a tiny seed starts to put down roots—the most essential thing for a plant's survival. She writes,

No risk is more terrifying than that taken by the first root. A lucky root will eventually find water, but its first job is to anchor … Once the first root is extended, the plant will never again enjoy any hope of relocating to a place less cold, less dry, less dangerous. Indeed, it will face frost, drought, and greedy jaws without any possibility of flight.

She calls taking root a big "gamble," but if the seed takes root it can go down twelve, thirty, forty meters. The results are powerful. The tree's roots can "swell and split bedrock, and move gallons of water daily for years, much more efficiently than any pump yet invented by man." If the root takes root, then the plant becomes all but indestructible: "Tear apart everything aboveground—everything—and most plants can still grow rebelliously back from just one intact root. More than once. More than twice."

Possible Preaching Angles: In the same way, every Christian needs to put down his or her roots into the soil of Christ's love. Or we need to put down roots into the soil of relationships—with a church family or in a marriage.
