6 Seek the Lord while he may be found, call upon him while he is near; 7 let the wicked forsake their way, and the unrighteous their thoughts; let them return to the Lord, that he may have mercy on them, and to our God, for he will abundantly pardon. 8 For my thoughts are not your thoughts, nor are your ways my ways, says the Lord. 9 For as the heavens are higher than the earth, so are my ways higher than your ways and my thoughts than your thoughts. 10 For as the rain and the snow come down from heaven, and do not return there until they have watered the earth, making it bring forth and sprout, giving seed to the sower and bread to the eater, 11 so shall my word be that goes out from my mouth; it shall not return to me empty, but it shall accomplish that which I purpose, and succeed in the thing for which I sent it. 12 For you shall go out in joy, and be led back in peace; the mountains and the hills before you shall burst into song, and all the trees of the field shall clap their hands. 13 Instead of the thorn shall come up the cypress; instead of the brier shall come up the myrtle; and it shall be to the Lord for a memorial, for an everlasting sign that shall not be cut off.

Commentary on Isaiah 55:6-13

(Read Isaiah 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.
