To live by His Word means that we are meant to grow. A flourishing life depends on healthy food, attentive care, and an intentional plan. 1 Corinthians 3 uses three different metaphors to illustrate how we need God’s Word to grow. We need solid food to become mature. We need God’s Word planted in us to produce a harvest. We need the word of Christ as the foundation to build our house strong. Without God’s Word, we are immature, unfruitful, and unproductive. If we do not put divine instruction into practice, we are easily led by the pattern of this world, overly conscious of ourselves, and ill-prepared for life’s greatest battles. The cost of not living by divine design proves very high.
