Decisions

The fundamental guidance which God gives to shape our lives—the instilling, that is, of the basic convictions, attitudes, ideals and value judgments, in terms of which we are to live—is not a matter of inward promptings apart from the Word but of the pressure on our consciences of the portrayal of God’s character and will in the Word, which the Spirit enlightens us to understand and apply to ourselves. J.I. Packer, Knowing God.

This then makes the reading of the Word necessary for true divine guidance in the usual sense. Reading and studying the Word then is mandatory for the believer in Jesus Christ. To do less, affects are lives by influencing our decisions in a negative way, leading to sin and mistakes that otherwise would be avoided.
