"Generous in Heart" teaches that generosity is about having a willing heart, not just giving money. Using Tracy's story, he shows how even small acts of generosity can have a big impact. Following 2 Corinthians 9, he explains six guidelines of generosity, emphasizing that giving should be done cheerfully, purposefully, and as obedience to God. The sermon challenges the congregation to live a life of generosity in all aspects, rooted in gratitude for God's grace.
