(11) So shall my word be . . .--The point of the comparison is that the predominance of fertility in the natural world, in spite of partial or apparent failures, is the pledge of a like triumph, in the long run, of the purposes of God for man's good over man's resistance. It does not exclude the partial, or even total, failure of many; it asserts that the saved are more than the lost. Comp. Isaiah 53:11.

Verse 11. - So shall my word be. God's word is creative. With the utterance the result is achieved. Hence the sublime passage, which even heathenism could admire (Longin., 'De Sublim.,' § 9), "And God said, Let there be light: and there was light" (Genesis 1:3). Hence, too, the more general statement, "By the Word of the Lord were the heavens made; and all the host of them by the breath of his mouth" (Psalm 33:6; comp. Psalm 148:5). But it shall accomplish; rather, unless it has accomplished. There is a mixture of two constructions, "It shall not return void," and "It shall not return unless it has accomplished," etc. It shall prosper. Every word that proceedeth out of the mouth of God has a prosperous course. It is endued with life from God, and (as Delitzsch says) "runs like a swift messenger through nature and the world of man, there to melt the ice, as it were, and here to heal and to save; and it does not return from its course till it has given effect to the will of the Sender. "The special "word" which the prophet has here in mind is the promise, so frequently given, of deliverance from Babylon and return in peace and joy to Palestine. But he carries his teaching beyond the immediate occasion, for the benefit of the people of God in all ages.

55:6-13 Here is a gracious offer of pardon, and peace, and of all happiness. It shall not be in vain to seek God, now his word is calling to us, and his Spirit is striving with us. But there is a day coming when he will not be found. There may come such a time in this life; it is certain that at death and judgment the door will be shut. There must be not only a change of the way, but a change of the mind. We must alter our judgments about persons and things. It is not enough to break off from evil practices, we must strive against evil thoughts. To repent is to return to our Lord, against whom we have rebelled. If we do so, God will multiply to pardon, as we have multiplied to offend. But let none trifle with this plenteous mercy, or use it as an occasion to sin. Men's thoughts concerning sin, Christ, and holiness, concerning this world and the other, vastly differ from God's; but in nothing more than in the matter of pardon. We forgive, and cannot forget; but when God forgives sin, he remembers it no more. The power of his word in the kingdoms of providence and grace, is as certain as in that of nature. Sacred truth produces a spiritual change in the mind of men, which neither rain nor snow can make on the earth. It shall not return to the Lord without producing important effects. If we take a special view of the church, we shall find what great things God has done, and will do for it. The Jews shall come to their own land; this shall represent the blessings promised. Gospel grace will make a great change in men. Delivered from the wrath to come, the converted sinner finds peace in his conscience; and love constrains him to devote himself to the service of his Redeemer. Instead of being profane, contentious, selfish, or sensual, behold him patient, humble, kind, and peaceable. The hope of helping in such a work should urge us to spread the gospel of salvation. And do thou help us, O Spirit of all truth, to have such views of the fulness, freeness, and greatness of the rich mercy in Christ, as may remove from us all narrow views of sovereign grace.So shall my word be that goeth forth out of my mouth,.... My good word, as the Targum; this may either be understood of Christ, the eternal Word, who is called the Word of God, and may be said to go forth out of his mouth, being spoken of by all his holy prophets, since the world began, whose coming was like the rain or snow, Hosea 6:3, he came from heaven, from his Father there, and as a free gift of his, and in consequence of a decree, as the rain does; the manner of his coming, like that, was suddenly, gratefully, and with great efficacy, watering his people with his grace, through the ministry of the word, and making them fruitful; and though he returned to heaven again, yet not empty, without fruit and effect; he produced a large harvest of souls, and procured all blessings of grace for them, and accomplished the whole will and pleasure of God, in effecting the salvation of his people; and the pleasure of the Lord prospered in his hand: or else it may be interpreted of God's word of promise; the promises are made in heaven, and come from thence as the rain and snow do; are the gifts of God's grace; are very refreshing and reviving, as rain to the earth; and are always effectual, being yea and amen in Christ Jesus; and being made good, fulfil purposes, or the good will and pleasure of God; particularly promises concerning Christ, pardon and peace through him; such as are given forth in this chapter: or rather it may be meant of the word of the Gospel, which is of God; comes from heaven; is a blessing grace; falls according to divine direction here and there; tarries not for the expectations, desires, or deserts of men; falls in great plenty; and is a blessing wherever it comes: it is the means of softening the hard hearts of men; of cooling the conscience set on fire by the law, and allaying the heat of divine wrath there; and of refreshing and reviving drooping, disconsolate, and weary souls: it is the means of the first buddings of grace in the Lord's people, and of the larger exercises and flourishings of it, and of all fruitfulness in good works: it is productive of seed to Christ the sower, and fruit to his ministers who labour under him, and of bread to the eater, the believer, whom it furnishes with the bread of life to feed upon by faith:

it shall not return to me void; it is accompanied with a divine energy; it is the power of God to salvation:

but it shall accomplish that which I please; in the conversion of sinners, and comfort of saints:

and it shall prosper in the thing whereto I sent it: whether it be the savour of life unto life, or the savour of death unto death; whether for the quickening of sinners, and reviving of saints; or whether for the hardening of men, and leaving them without excuse to perish in their sins, both in the Jewish and Gentile world.
