(4.) That his great undertaking shall be successful and shall answer expectation: The pleasure of the Lord shall prosper in his hand. God's purposes shall take effect, and not one iota or tittle of them shall fail. Note, [1.] The work of man's redemption is in the hands of the Lord Jesus, and it is in good hands. It is well for us that it is in his, for our own hands are not sufficient for us, but he is able to save to the uttermost. It is in his hands who upholds all things. [2.] It is the good pleasure of the Lord, which denotes not only his counsel concerning it, but his complacency in it; and therefore God loved him, and was well pleased in him, because he undertook to lay down his life for the sheep. [3.] It has prospered hitherto, and shall prosper, whatever obstructions or difficulties have been, or may be, in the way of it. Whatever is undertaken according to God's pleasure shall prosper, ch. xlvi. 10. Cyrus, a type of Christ, shall perform all God's pleasure (ch. xliv. 28), and therefore, no doubt, Christ shall. Christ was so perfectly well qualified for his undertaking, and prosecuted it with so much vigour, and it was from first to last so well devised, that it could not fail to prosper, to the honour of his Father and the salvation of all his seed.
