These are the mercies promised, and in these God does great things (v. 21), He deals wondrously with his people, v. 26. Herein he glorifies his power, and shows that he can relieve his people though their distress be ever so great, and glorifies his goodness, that he will do it upon their repentance though their provocations were ever so great. Note, When God deals graciously with poor sinners that return to him it must be acknowledged that he deals wondrously and does great things. Some expositors understand these promises figuratively, as pointing at gospel-grace, and having their accomplishment in the abundant comforts that are treasured up for believers in the covenant of grace and the satisfaction of soul they have therein. When God sends us his promises to be the matter of our comfort, his graces to be the grounds of it, and his Spirit to be the author of it, we may well own that he has sent us (according to his promise here, v. 19) corn, and wine, and oil, or that which is unspeakably better, and we have reason to be satisfied therewith.
