New Growth in Settled Places

For nearly a century, neuroscience operated under an iron law: adult brains cannot grow new neurons. The great Spanish neuroscientist Santiago Ramón y Cajal declared in 1928 that the nerve paths of the adult brain were "fixed, ended, immutable." Once you reached adulthood, what you had was what you got. No new growth. No second chances. The scientific world accepted this as settled fact for seventy years.

Then in 1998, researchers Peter Eriksson and Fred Gage published a study that shattered the old certainty. They discovered that the adult human brain does, in fact, generate new neurons — particularly in the hippocampus, the region responsible for learning and memory. The brain was never as imprisoned as everyone believed. New life was quietly growing in places the experts had declared closed.

Some of us have accepted a similar verdict about our own souls. We have heard — from others, or from our own weary inner voice — that we are fixed, ended, immutable. That the patterns we have fallen into are permanent. That the chains we carry are simply who we are now.

But the God who spoke light into darkness is not bound by old diagnoses. The same Creator who wove neurogenesis into the fabric of our biology is able to do a new thing in your spirit. "If anyone is in Christ," Paul writes, "the new creation has come. The old has gone, the new is here."

You are not stuck. The Almighty is still growing new life in places everyone else gave up on — including you.
