The Bible is a single Book, from the mind of a single Author. It tells a single story, and it does so within the framework of a single, powerful structure. That story and structure are God’s covenant.
Wisdom and counsel can be found in Jeremiah’s letter to the exiles in Babylon. His instructions for them ring true for us today, as we take up our callings to the Kingdom and glory of God, to live as witnesses to Christ and ambassadors of His Kingdom.
The Law of God serves as the rule book of the soul, the repository of values and default choices to which the conscience appeals in bringing mind and heart together for action in love.
The mind receives and processes information, while the heart stores and deploys affections. In the soul, these overlap and interact, but they require the conscience to help them process ideas and feelings into actions.
