Fasting is a spiritual discipline that involves abstaining from food or other comforts to draw closer to God. This verse teaches that fasting should be a private act of devotion, not a public display. The focus is on the relationship between the individual and God, rather than seeking attention or praise from others. By emphasizing that God, who is unseen, observes and rewards what is done in secret, it highlights the value of sincerity and authenticity in one's spiritual practices.
This teaching encourages believers to cultivate a personal and genuine faith, free from the desire for external validation. It underscores the importance of inner transformation over outward appearances. In a broader sense, this principle can be applied to other areas of spiritual life, reminding us that true devotion is about the heart's intention rather than external recognition. By fostering a sincere relationship with God, believers can experience spiritual growth and receive divine rewards that are not bound by human perception.
