Prayers belong strictly to the worship of God. Fasting is a subordinate aid, which is pleasing to God no farther than as it aids the earnestness and fervency of prayer.
John CalvinThe Lord commands us to do good unto all men without exception, though the majority are very undeserving when judged according to their own merits. But scripture here helps us out with an excellent argument when it teaches us that we must not think of man's real value, but only of his creation in the image of God to which we owe all possible honor and love.
John CalvinSince no daily responses are given from heaven, and the Scriptures are the only record in which God has been pleased to consign His truth to perpetual remembrance, the full authority which they ought to possess with the faithful is not recognized unless they are believed to have come from heaven as directly as if God had been heard giving utterance to them.
