The document discusses the parable of the sower from the Bible, in which seeds sown by a sower produced different results depending on the type of soil. It says Jesus places responsibility on individuals for their differing spiritual results. It then discusses that no one is fully spiritually mature upon becoming Christian, and that individuals are responsible for their own spiritual growth through learning practices like prayer, Bible reading, worship, sharing their faith, and resisting sin. Spiritual maturity requires both knowing spiritual truths and putting them into practice.
