ANSWER: The Revision is more exact: "Be not anxious." Perfect trust in God cannot dwell in the same heart with worry about the future. Where the great purpose of life is to promote the kingdom of God and to obtain the righteousness which he requires and bestows — if this is our chief good, the inferior good of material things will be added. For the Christian virtues are economic, promoting health, industry, frugality, a sufficiency, and often an overplus for Christian charities and Gospel missions.
