Introduction

This verse is part of Christ's teachings during the Sermon on the Mount, where He instructs His followers on the principles of true righteousness and piety. Fasting, as an act of devotion, is addressed here with a focus on the inner life of the believer rather than outward appearances.

Insights from Commentaries

• Matthew Henry's Commentary

  Matthew Henry emphasizes that fasting is an act designed to bring the believer closer to God; it should be devoid of ostentation. He warns against the Pharisaic tendency to perform religious acts for the sake of public approval. Instead, true fasting should reflect a humble heart seeking God in secret. Henry posits that the act of fasting must come from sincerity rather than the desire for public recognition.

• Albert Barnes' Notes on the Bible

  Barnes elucidates that the focus of fasting should be on God rather than on man. He discusses how the practice was commonly mismanaged in the time of Christ, where fasting was often performed with a focus on being seen rather than on spiritual significance. Barnes makes a pivotal point that those who seek the applause of men may receive their reward in earthly terms but will miss the eternal benefits that come from God when the act is done discreetly.

• Adam Clarke's Commentary

  Clarke provides a detailed explanation of the cultural context of fasting during the time of Christ. He points out that fasting was a common practice among the Jews, but Christ calls for a more profound, heart-centered approach. Clarke notes that fasting should be an intimate practice between the individual and God, emphasizing the Father’s promise to reward those who fast in secret. He highlights that the essence of this teaching is to redirect focus from human approval to divine relationship.

Theological Significance

The theological implications of Matthew 6:18 are profound. It speaks to the heart of worship and devotion, inviting believers to engage in practices that build intimacy with God rather than seeking validation from others. This verse underscores the principle that God values the motivation and intent behind our actions — a solitary, humble heart is far more precious in His sight than a publicly acclaimed performance.

Application for Believers

• Private Devotion:

  Believers are encouraged to engage in acts of piety such as prayer and fasting privately, creating a personal space for communion with God. This private devotion can cultivate a deeper faith and genuine spiritual growth.

• Sincerity Over Show:

  The call to sincerity reminds Christians that actions within the faith should not be performed for social status or recognition. This principle is salient for teaching authenticity in the church.

• Rewards from God:

  Understanding that rewards come from God when actions are performed in secret can provide reassurance and motivation. Believers can trust that God sees their sacrifices and will reward them not by worldly standards but in the ways that matter eternally.

Conclusion

In summary, Matthew 6:18 invites believers to examine their hearts regarding spiritual practices. Christ's teaching serves as a powerful reminder that genuine spirituality is cultivated in private, away from the eyes of men, where the believer can experience true intimacy with the Father. Pastors and leaders are encouraged to instill these values in their congregations, promoting a culture of authentic faith that esteems inner devotion over outward appearances.
