12. Then spoke Joshua to the Lord, etc Such is the literal reading, but some expound it as meaning before Jehovah: for to speak to God, who, as piety dictates, is to be suppliantly petitioned, seems to be little in accordance with the modesty of faith, and it is immediately subjoined that Joshua addressed his words to the sun. I have no doubt that by the former clause prayer or vow is denoted, and that the latter is an expression of confidence after he was heard: for to command the sun to stand if he had not previously obtained permission, would have been presumptuous and arrogant. He first, then, consults God and asks: having forthwith obtained an answer, he boldly commands the sun to do what he knows is pleasing to God.
And such is the power and privilege of the faith which Christ inspires, (Matthew 17:20; Luke 17:6) that mountains and seas are removed at its command. The more the godly feel their own emptiness, the more liberally does God transfer his power to them, and when faith is annexed to the word, he in it demonstrates his own power. In short, faith borrows the confidence of command from the word on which it is founded. Thus Elias, by the command of God, shut and opened the heaven, and brought down fire from it; thus Christ furnished his disciples with heavenly power to make the elements subject to them.
Caution, however, must be used, lest any one may at his own hand presume to give forth rash commands. Joshua did not attempt to delay and check the course of the sun before he was well instructed as to the purpose of God. And although, when he is said to have spoken with God, the words do not sufficiently express the modesty and submission which become the servant of God in giving utterance to his prayers, let it suffice us briefly to understand as implied, that Joshua besought God to grant what he desired, and on obtaining his request, became the free and magnanimous herald of an incredible miracle unlike any that had previously taken place. He never would have ventured in the presence of all to command the sun so confidently, if he had not been thoroughly conscious of his vocation. Had it been otherwise, he would have exposed himself to a base and shameful affront. When, without hesitation, he opens his mouth and tells the sun and the moon to deviate from the perpetual law of nature, it is just as if he had adjured them by the boundless power of God with which he was invested. Here, too, the Lord gives a bright display of his singular favor toward his Church. As in kindness to the human race he divides the day from the night by the daily course of the sun, and constantly whirls the immense orb with indefatigable swiftness, so he was pleased that it should halt for a short time till the enemies of Israel were destroyed.

(94) One might almost suspect from this concluding sentence, that Calvin was a stranger to the Copernican system, and still continued to believe that it was not the earth but the sun that revolved. As we know, however, that he was before his age in many points, so we cannot believe that he was behind it in this. — Ed.
