In this sermon on Matthew 6:16-18, Pastor Jamie considers the significance of fasting in the Christian life, aligning it with righteousness, prayer, and giving. Jesus teaches that fasting, like other acts of worship, must be done with a sincere heart and in secret, rather than for public recognition. The sermon contrasts genuine righteousness, which seeks to honor God, with outward religiosity that seeks approval from others. It encourages believers to fast not just to temper physical appetites but to deepen their hunger for God, aligning their hearts with spiritual priorities.
