Biologist Bruce Lipton says “Genes do not self-activate… Perception controls genes.” The state of your health is NOT determined by your genes. It is signals from your environment that determine the activation of your genes.
He also speaks about “adaptive mutation,” which means that genes do not change randomly, but in response to the environment, or perception. But our perceptions may be accurate or inaccurate, hence the title of his book, The Biology of Belief. Perception will rewrite your genes according to what you believe.
Is this where faith comes into play? Jesus said:
“I tell you the truth, if you have faith as small as a mustard seed, you can say to this mountain, “Move from here to there” and it will move.” — Matthew 17:20
