12. …“Who covereth the heaven with clouds, who prepareth rain for the earth” (ver. 8). Now thou art alarmed, because thou canst not see the heaven: when it hath rained thou shalt gather fruit, and shalt see clear sky. Perhaps our God hath done this. For had we not the obscurity of Scripture as an occasion, we should not say to you those things wherein ye rejoice. This then perhaps is the rain whereat ye rejoice. It would not be possible for it to be expressed to you by our tongue, were it not that God covereth with clouds of figures the heaven of the Scriptures. For this purpose willed He that the words of the Prophets should be obscure, that the servants of God might afterwards have that by interpreting which they might flow over the ears and hearts of men, that they might receive from the clouds of God the fatness of spiritual joy. “Who maketh grass to grow upon the mountains, and herb for the service of men.” Behold the fruit of the rain. “Who maketh,” saith he, “grass to grow upon the mountains.” Doth it not also grow upon the low ground? Yes, but it is a great thing that it groweth “on the mountains.”…For nothing could be more barren than the hard mountains. “And herb for the service of men.” What “service”? Listen to Paul himself. “And ourselves,” saith he, “your servants for Jesus Christ’s sake.” He who said, “If we have sown unto you spiritual things, is it a great thing if we reap your carnal things?” yet said, that he was a “servant.” For we are your servants, brethren. Let none of us speak of himself, as though he were greater than you. We shall be greater if we are more humble. “But whosoever will be great among you” (it is the Lord’s saying), “shall be your servant.” Paul the Apostle, indeed, living by his own labour, refused even to receive “the grass of the mountains;” he chose to want; nevertheless, the mountains gave “grass.” Because he chose not to receive, ought the mountains therefore not to give, and so to remain barren? Fruit is due to the rain, food is due to the servant, as the Lord saith, “Eat such things as they give you:” and that they should not think that they gave aught of their own, He added, “for the labourer is worthy of his hire.”
