The Mind

Ecclesiastes 2:12 Then I turned my thoughts to consider wisdom, and also madness and folly. What more can the king’s successor do than what has already been done?

The brain is the physical representation of the mind. The health of the brain is directly related to the health of the mind. A healthy mind equals a healthy brain. A healthy mind is a mind that thinks truthfully. 

The ultimate outcome of representing God (thinking truthfully) is life, the ultimate outcome of misrepresenting God (thinking untruthfully ) is death  .

Proverbs 10:16 The wages of the righteous is life, but the earnings of the wicked are sin and death.
