In 1st Samuel 30, David displayed an attitude of gratitude toward his fellow soldiers since the Lord had rescued the women and children that the Amalekites had taken. David realized how much he could be grateful for and he extended that to others who needed it as well. In Luke 17 when Jesus healed the 10 lepers, only one of them, a Samaritan, went back and praised the Lord. Faithfulness leads to thankfulness that leads to humility so we can see clearly.
