Jesus went across enemy lines and shed his blood to cleanse us from all sin. In 2 Samuel 23, David's mighty warriors risked their lives to cross enemy lines and bring back water that David longed for from his hometown of Bethlehem. David refused to drink the water because the water represented the men's blood. There was a culture of love with David and his men. The culture of love starts with Jesus and he gave his life for us, so we should do things for the Lord out of an overflow of the example he set in love.
