A thankful spirit is a source of joy

A thankful spirit is a source of joy, whereas an unthankful spirit is a source of sadness. Being grateful for a gift preserves the gift, otherwise we will lose it. Also, when tested by some trial you should try to find out not why or through whom it came, but only how to endure it gratefully, without distress or rancor.
