Rejoicing 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 CalvinThe Fanaticism which discards the Scripture, under the pretense of resorting to immediate revelations is subversive of every principle of Christianity. For when they boast extravagantly of the Spirit, the tendency is always to bury the Word of God so they may make room for their own falsehoods.
John CalvinWe are surrounded by God’s benefits. The best use of these benefits is an unceasing expression of gratitude.
