We are beginning to look at the bible's teaching on what is best for a healthy mind. We look at Paul's inspired analysis of society: wilful exclusion of God/ the bible/ the light of conscience from our thoughts leads to ignorance, darkness, separation from God and futile thinking. Our minds are no longer working rationally. This leads us into sinful living governed by desires and lusts, not by the light of God. We see how what we need is to turn back to God, that with Jesus we may be restored to our right minds.
