Naaman the Syrian and the Samaritan were both lepers, healed by the power of God even though they were foreigners. But their response of gratitude was more important than their nationalities or their disease.
Gratitude is the foundation of stewardship. Our thankfulness to God for our life and our spiritual healing through Christ as well as for all the gifts of time, talent, and treasure we have received should motivate our entire life. Or will we be like the other nine lepers who were healed, and not bother to give thanks? Our response will determine the sort of stewards we are.
