Nowhere in the Bible can we find either ingratitude or joylessness commanded or commended. All ungrateful feelings and dispositions are condemned. A great deal is said in disapproval of murmuring, discontent, worrying, and all forms of ingratitude. Again and again we are taught that joy is the keynote of a true life. It is not enough to rejoice when the sun shines, when all things are going well with us, when we are in the midst of prosperity; we are to rejoice as well when clouds hide the blue sky, when our circumstances seem to be adverse, or when we are passing through sufferings.
