30:18-24 We have here further intimations of the favour of God for them after the days of their calamity have expired. The proper work and office of Christ, as Mediator, is to draw near unto God, for us, as the High Priest of our profession. His own undertaking, in compliance with his Father's will, and in compassion to fallen man, engaged him. Jesus Christ was, in all this, truly wonderful. They shall be taken again into covenant with the Lord, according to the covenant made with their fathers. I will be your God: it is his good-will to us, which is the summary of that part of the covenant. The wrath of God against the wicked is very terrible, like a whirlwind. The purposes of his wrath, as well as the purposes of his love, will all be fulfilled. God will comfort all that turn to him; but those who approach him must have their hearts engaged to do it with reverence, devotion, and faith. How will they escape who neglect so great salvation?The fierce anger of the Lord shall not return,.... This explains what is meant by the continuing whirlwind in Jeremiah 30:23;

until he hath done it; his whole will and pleasure; brought Babylon to ruin, and destroyed all the antichristian powers:

and until he hath performed the intents of his heart; in a way of grace and mercy to his people, and in a way of wrath and vengeance on their enemies:

in the latter day ye shall consider it; this prophecy, and understand it; and see it wholly and fully accomplished.
