Charles Finney addresses the 'Hardness of Heart' in his sermon, emphasizing how the disciples, despite witnessing miracles, failed to understand due to their hardened hearts. He explains that hardness of heart is a voluntary state of mind, influenced by selfishness, which blinds individuals to truth and affects their feelings and judgments. Finney illustrates this with examples from scripture and personal observations, showing that a hard heart leads to misunderstanding, delusion, and a lack of genuine faith. He urges listeners to self-examine and recognize the state of their hearts, as true revival and understanding come from a softened heart open to God's truth.

John Chrysostom preaches on Jesus' compassion for the multitude, highlighting how He first healed them before providing food, showing His benevolence and providence. Despite the disciples' lack of understanding, Jesus patiently leads them to faith through questioning and miracles, rebuking their hardened hearts and lack of recollection. He emphasizes the importance of discerning the signs of the times and warns against the hypocrisy of seeking signs from Heaven. Through strong reproof and gentle reminders, Jesus guides His disciples away from earthly concerns to focus on spiritual matters and the teachings of the Pharisees and Sadducees.

Favell Lee Mortimer delves into the importance of understanding spiritual truths by reflecting on how Jesus' disciples struggled to grasp His teachings, like the analogy of leaven. Their lack of faith and spiritual understanding stemmed from hidden unbelief in their hearts, which displeased Jesus. He warns against false doctrines, comparing the Pharisees and Sadducees to modern-day groups preaching misleading teachings that can corrupt minds and hearts. Mortimer emphasizes the need to discern good doctrine that exalts Christ and humbles man, as it is the foundation of true faith and spiritual growth.
