This is a subsidiary post of Self-Control.
Control these two faculties and you can control your entire being and behavior. This is because through the heart we control the mouth (Matthew 12:34; Luke 6:45), and through the mouth we control the body (James 3:2-5). This post is about a combined focus on heart and mouth.
Romans 10:8, 9, 10 – Note that each of these three verses makes mention of both heart and mouth.
James 3:2-12 – There is an allusion to the heart in James 3:11-12.
Ezekiel 33:30, 31, 32, 33
