The story of ten lepers healed by Jesus reveals a profound truth about salvation and gratitude. While all ten men were physically healed of their leprosy, only one returned to thank Jesus - a Samaritan who was doubly despised by society. Jesus declared that this man's faith had brought him salvation, not just healing. The difference was thanksgiving. The other nine suffered from what we might call the ninth disease: ingratitude. They felt entitled to their healing rather than recognizing it as an unmerited gift. This teaches us that salvation requires more than just receiving God's blessings - it demands a heart that actively expresses gratitude through thanksgiving.
