The brain is remarkably small, but stress can make it even smaller. Recent research has revealed that cumulative stress can shrink the prefrontal cortex, the part of the brain responsible for managing emotions, impulses, and social interactions. This shrinkage is linked to anxiety and depression, highlighting the toll that a lifetime of stress can take. But there’s good news—the brain’s plasticity allows it to heal through intentional practices like exercise, meditation, and meaningful relationships. The psalmist in Psalm 119 understood this idea of growth and healing after facing stress and hardship, “It was good for me to be afflicted so that I might learn your decrees” (v. 71). Affliction, though painful, became the psalmist’s teacher—taking us from being “astray” from God to choosing to “obey [His] word” (v. 67). The psalmist expresses gratitude for his bitter medicine and God’s goodness (v. 68). While he understood that affliction and suffering could diminish him, he trusted God to use those experiences to refine and restore him (v. 66). Like our brains, our spirits are capable of being stretched. God uses this stretching to cause growth and renewal. Through Scripture, prayer, and a Spirit-inspired perspective, God can reverse the effects of our hardships. He can use our afflictions for our spiritual growth, transforming pain into purpose.
