It is work as free from care and toil and fatigue as is the wing-stroke of the jubilant lark when it soars into the sunlight of a fresh, clear day and, spontaneously and for self-relief, pours out its thrilling carol. Work [in heaven] is a matter of self-relief, as well as a matter of obedience to the ruling will of God. It is work according to one’s tastes and delight and ability. If tastes vary there, if abilities vary there, then occupations will vary there (David Gregg).
