Thanksgiving-the giving of thanks-to God for all His blessings should be one of the most distinctive marks of the believer in Jesus Christ. We must not allow a spirit of ingratitude to harden our heart and chill our relationship with God and with others.Nothing turns us into bitter, selfish, dissatisfied people more quickly than an ungrateful heart. And nothing will do more to restore contentment and the joy of our salvation than a true spirit of thankfulness.In the ancient world, leprosy was a terrible disease. It hopelessly disfigured those who had it, and it permanently cut them off from normal society. Without exception, every leper yearned for one thing: To be healed.One day 10 lepers approached Jesus outside a village, loudly pleading with Him to heal them. In an instant He restored them all to perfect health-but only one came back and thanked Him. All the rest left without a word of thanks, their minds preoccupied only with themselves, gripped with a spirit of ingratitude.Today, too, ingratitude and thanklessness are far too common. Children forget to thank their parents for all that they do. Common courtesy is scorned. We take for granted the ways that God & others help us.
