Thankfulness is not a minor virtue. It is not one of the elementary virtues [that] may be left behind as we become more mature. I believe that thankfulness is essential to the strength of every virtue, and that without it every other branch is starved and lean.
Life without thankfulness is devoid of love and passion. Hope without thankfulness is lacking in fine perception. Faith without thankfulness lacks strength and fortitude. Every virtue divorced from thankfulness is maimed and limps along the spiritual road.
—John Henry Jowett
