Joshua 1:9

Have not I commanded thee? Be strong and of a good courage; be not afraid, neither be thou dismayed; for the Lord, thy God, is with thee whithersoever thou goest. Thus the assurance gains in strength when to the positive command to be courageous is added the negative to lay aside all fear, as in Deuteronomy 31:6. We Christians have a similar promise of victory over all our enemies and the eventual enjoyment of the heavenly happiness. But we also have the command of God to read, study, and hear the Word of God to arrange our whole life in accordance with its precepts. Then we also shall have success in the things we undertake under the guidance of God.
