Scientific research over the last 30 years has found that the brain is the largest gland in the body. It releases at least a thousand chemicals into the body at different times, and the depth of its effect on the body is still not completely known.

Even in the natural process of healing our thought life plays a direct role in the chemicals released into the rest of the body. Certain thoughts can be toxic killers if allowed to make deep ruts in our thinking. Lust, anger, hatred, envy, and jealousy are all strong thought patterns.

Thoughts can be deadly. The Scriptures warn that in the last days men’s hearts will fail them for fear. The increase in heart attacks in this generation is probably due to the stress, worry, anxiety, fears, and negative information we allow ourselves to dwell on all day long. We have a choice to replace thoughts of doubt in our hearts with positive ideas, dreams, and good, pleasant, and lovely reports (Philippians 4:8).
