Our thoughts are far more than how we feel—they create real, measurable changes in the body.
Decades of research, including a major meta-analysis by Segerstrom and Miller (2004), shows that psychological stress significantly weakens the immune system, especially the cells responsible for fighting viruses, cancer, and infection. Stress reduces the activity of natural killer cells, T-cells, and other immune defenders, while also contributing to sleep disruption and unhealthy habits that further compromise the body.
This scientific insight aligns with Scripture’s teaching that we are integrated beings—spirit, soul, and body—and that emotions and attitudes directly influence physical health. Proverbs 17:22 describes this reality plainly: a joyful heart promotes healing, while a crushed spirit harms the body.
Negative emotions such as fear, anger, grief, bitterness, and loneliness can place stress on specific organs, including the heart, kidneys, liver, lungs, and gallbladder. But the good news is that God gives us tools for renewal—prayer, forgiveness, gratitude, community, and the intentional directing of our thoughts.
Understanding the power of our thoughts is a pathway to better health.
