Isaiah 43:21

1. Omissions of the good which God had commanded; and this part of the charge is here much insisted upon. Observe how it comes in with a but; compare v. 21, where God tells them what favours he had bestowed upon them and what his just expectations were from them. He had formed them for himself, intending they should show forth his praise. But they had not done so; they had frustrated God's expectations from them, and made very ill returns to him for his favours. For, (1.) They had cast off prayer: Thou hast not called upon me, O Jacob! Jacob was a man famous for prayer (Hosea 12 4); his seed bore his name, but did not tread in his steps, and therefore are justly upbraided with it. God takes it ill when children degenerate from the virtue and devotion of their pious ancestors. To boast of the name of Jacob, and yet live without prayer, is to mock God and deceive ourselves. If Jacob does not call upon God, who will? (2.) They had grown weary of their religion: "Thou art Israel, the seed not only of a praying but of a prevailing father, that was a prince with God; and yet, not valuing his experiences any more than his example, thou hast been weary of me." They had been in relation to God, employed in his service and in communion with him; but they began to snuff at it, and to say, Behold, what a weariness is it! Note, Those who neglect to call upon God do in effect tell him they are weary of him and have a mind to change their Master. (3.) They grudged the expense of their devotion, and were niggardly and penurious in it. They were for a cheap religion; and in those acts of devotion that were costly they desired to be excused. They had not brought, no, not their small cattle, the lambs and kids, which God required for burnt-offerings (v. 23), much less did they bring their greater cattle, pretending they could not spare them, they must have them for the maintenance of their families. So little sense had they of the greatness of God and their obligations to him that they could not find in their hearts to part with a lamb out of their flock for his honour, though he called for it and would graciously have accepted it. Sweet cane, or calamus, was used for the holy oil, incense, and perfume; but they were not willing to be at the charge of that, v. 24. What they had must serve, though it was old and good for nothing; they would not buy fresh. Perhaps it was usual for devout pious persons to bring free-will incense as well as other free-will offerings; but they were not so generous, nor did they fill the altar of God, nor moisten it abundantly, as they should have done, with the fat of their sacrifices; what sacrifices they did bring were of the lean and refuse of their cattle, that had no fat in them to regale the altar with. (4.) What sacrifices they did offer they did not honour God with them, and so they were, in effect, as no sacrifices (v. 23): Neither hast thou honoured me with thy sacrifices. Some of them offered their sacrifices to false gods; others, who offered them to the true God, were either careless in the manner of offering them or hypocritical in their intentions, so that they might be truly said not to honour God with them, but rather to dishonour him. (5.) That which aggravated their neglect of sacrificing was that, as God had appointed it, it was no burdensome thing; it was not a service that they had any reason at all to complain of: "I have not caused thee to serve with an offering; I have not made it a task and drudgery to you, whatever you, through the corruption of your natures, have made it yourselves. I have not wearied thee with incense." None of God's commandments are grievous, no, not those concerning sacrifice and incense. They were not more costly than might be afforded by those that lived in such a plentiful country, nor did their attendance on them require any more time than they could well spare. But that which especially forbade them to call it a wearisome service was that they were required to be cheerful and pleasant, and to rejoice before God in all their approaches to him, Deut 12 12. They had many feasts and good days, but only one day in all the year in which they were to afflict their souls. The ordinances of the ceremonial law, though, in comparison with Christ's easy yoke, they are spoken of as heavy (Acts 15 10), yet, in comparison with the service that idolaters did to their false gods, they were light, and not to be called services nor found fault with as wearisome. God did not require them to sacrifice their children, as Moloch did.

Verses 14-21 The deliverance from Babylon is foretold, but there is reference to greater events. The redemption of sinners by Christ, the conversion of the Gentiles, and the recall of the Jews, are described. All that is to be done to rescue sinners, and to bring the believer to glory, is little, compared with that wondrous work of love, the redemption of man.
