It is permissible to use wine not only for necessity, but also to make us merry...... [it must be moderate] lest men forget themselves, drown their senses,.....in making merry [those who enjoy wine] feel a livelier gratitude to God.
John CalvinRejoicing refers to moderation of spirit when the mind keeps itself in calmness under adversity and does not give indulgence to grief. Constant praying is the way of 'rejoicing perpetually', for by this means we ask from God alleviation in connection with all our distresses.
John Calvin
