How do I grow my faith? From a Biblical perspective, we don't do the growing at all. That is the power of the Holy Spirit at work in our lives as God's grace comes to us in Word and Sacrament. We can, however, put ourselves in a position to grow in our faith, and this begins by accepting the King's gracious invitation to come to the wedding banquet of his Son. We are to come dressed appropriately for this great occasion, clothed in the garment which the King himself provides: the righteousness of his own Son.
