28:29 This also - This part of the husbandman's discretion. These words contain the application of the similitude. The husbandman manages his affairs with common discretion; but God governs the world, and his church, with wonderful wisdom: he is great and marvellous, both in the contrivance of things, and in the execution of them.
28:23-29 The husbandman applies to his calling with pains and prudence, in all the works of it according to their nature. Thus the Lord, who has given men this wisdom, is wonderful in counsel, and excellent in his working. As the occasion requires, he threatens, corrects, spares, shows mercy, or executes vengeance. Afflictions are God's threshing instruments, to loosen us from the world, to part between us and our chaff, and to prepare us for use. God will proportion them to our strength; they shall be no heavier than there is need. When his end is answered, the trials and sufferings of his people shall cease; his wheat shall be gathered into the garner, but the chaff shall be burned with unquenchable fire.
