Fasting is a spiritual discipline intended to deepen one's relationship with God. Jesus emphasizes the importance of sincerity in this practice. He criticizes those who fast merely to gain attention and admiration from others, describing them as hypocrites. By disfiguring their faces, they make their fasting obvious, seeking human praise rather than divine connection. Jesus points out that such individuals have already received their reward, which is the temporary approval of people.
In contrast, Jesus encourages a more private and genuine approach to fasting. The focus should be on the inner transformation and spiritual benefits that come from dedicating time to God. This teaching is a call to authenticity in one's spiritual life, reminding believers that true rewards come from God, not from human recognition. By fasting with a sincere heart, believers can experience a deeper, more meaningful relationship with God, free from the distractions of seeking external validation.
