A.W. Pink emphasizes the necessity of an honest heart in receiving God's Word, arguing that both the Divine Law and the Gospel must be balanced in preaching to avoid misleading believers. He warns against the dangers of superficial faith and the importance of genuine self-examination, urging Christians to seek a heart transformed by grace that loves truth and bears fruit. Pink highlights the four types of hearers in the Parable of the Sower, ultimately focusing on the 'good ground' hearers who possess an honest and good heart, which is essential for true spiritual growth and understanding. He stresses that an honest heart is characterized by a sincere desire for truth, acceptance of God's diagnosis of sin, and a commitment to live in accordance with God's will.
