The margins of excellence

"Pursuing excellence doesn’t mean overloading every minute of our schedule. It means creating space for God to guide, correct, and inspire." —Dr. Greathouse

As a cancer biologist and dietitian, I spend my days investigating the intricate systems of the human body—how cells communicate, how they go awry, and how we might restore them to health with the right nutrients. Excellence in science requires precision, persistence, and long hours. Yet, I’ve learned that in both research and life, the most important discoveries often happen in the margins—when you least expect it...

In scripture, we see that Jesus never rushed. He left room for interruptions—healing a bleeding woman on his way to Jairus’ house, pausing to feed a crowd, or withdrawing to pray in solitude. In our drive for academic success, research productivity, and career advancement, we can forget that God works most powerfully not just in our peak performances but in the quiet, unstructured spaces we allow Him to inhabit—in relationship with one another.

Pursuing excellence doesn’t mean overloading every minute of our schedule. It means creating space for God to guide, correct, and inspire. In my own field, the most innovative ideas don’t come when I’m pushing through yet another deadline—they arrive in the stillness, when I pause, reflect, and invite God into the process.

Leaving margins—mentally, physically, and spiritually—is an act of trust. It says, “Lord, I will do my part, but I trust You to fill in the gaps.” Whether you’re grading, researching, studying, or leading, let your calendar—and your heart—have room for the Holy Spirit to move.

“In quietness and trust is your strength.” – Isaiah 30:15

Let us strive for excellence, not exhaustion—faithfully working while also faithfully waiting, leaving space for the Creator to do what only He can.
