Came across this quote recently in some reading I am doing.

Since faith fastens on God’s benevolence, it yields gratitude, which in turn sponsors risk-taking in the service of others. Grateful people want to let themselves go; faithful people dare to do it. People tethered by to God by faith let themselves go because they know they will get themselves back.
Grateful people overflow a little, especially with thanksgiving and passed-on kindness. But they do not therefore lack discipline. In fact, self-indulgence tends to suppress gratitude; self-discipline tends to generate it.
