Therefore hath he mercy on whom he will have mercy, and whom he will he hardeneth.
God’s different dealing with men. He hath mercy on some, and hardeneth others. When God is here spoken of as hardening some of the children of men, it is not to be understood that God by any positive efficiency hardens any man’s heart. There is no positive act in God, as though he put forth any power to harden the heart. To suppose any such thing would be to make God the immediate author of sin. God is said to harden men in two ways: by withholding the powerful influences of his Spirit, without which their hearts will remain hardened, and grow harder and harder; in this sense he hardens them, as he leaves them to hardness. And again, by ordering those things in his providence which, through the abuse of their corruption, become the occasion of their hardening. Thus God sends his word and ordinances to men which, by their abuse, prove an occasion of their hardening. So the apostle said, that he was unto some “a savour of death unto death.” So God is represented as sending Isaiah on this errand, to make the hearts of the people fat, and to make their ears heavy, and to shut their eyes; lest they should see with their eyes, and hear with their ears, and understand with their heart, and convert, and be healed. Isaiah 6:10. Isaiah’s preaching was, in itself, of a contrary tendency, to make them better. But their abuse of it rendered it an occasion of their hardening. As God is here said to harden men, so he is said to put a lying spirit in the mouth of the false prophets. II Chronicles 18:22.
That is, he suffered a lying spirit to enter into them. And thus he is said to have bid Shimei curse David. II Samuel 16:10. Not that he properly commanded him; for it is contrary to God’s commands. God expressly forbids cursing the ruler of the people. Exodus 22:28. But he suffered corruption at that time so to work in Shimei, and ordered that occasion of stirring it up, as a manifestation of his displeasure against David.
God may save any …without prejudice to the honour of his holiness. God is an infinitely holy being. The heavens are not pure in his sight. He is of purer eyes than to behold evil, and cannot look on iniquity. And if God should in any way countenance sin, and should not give proper testimonies of his hatred of it, and displeasure at it, it would be a prejudice to the honour of his holiness. But God can save the greatest sinner without giving the least countenance to sin. If he saves one, who for a long time has stood out under the calls of the gospel, and has sinned under dreadful aggravations; if he saves one who, against light, has been a pirate or blasphemer, he may do it without giving any countenance to their wickedness; because his abhorrence of it and displeasure against it have been already sufficiently manifested in the sufferings of Christ. It was a sufficient testimony of God’s abhorrence against even the greatest wickedness, that Christ, the eternal Son of God, died for it. Nothing can show God’s infinite abhorrence of any wickedness more than this. If the wicked man himself should be thrust into hell, and should endure the most extreme torments which are ever suffered there, it would not be a greater manifestation of God’s abhorrence of it, than the sufferings of the Son of God for it.
God may save any sinner whatsoever consistently with his justice. The justice of God requires the punishment of sin. God is the Supreme Judge of the world, and he is to judge the world according to the rules of justice. It is not the part of a judge to show favour to the person judged; but he is to determine according to a rule of justice without departing to the right hand or left. God does not show mercy as a judge, but as a sovereign. And therefore when mercy sought the salvation of sinners, the inquiry was how to make the exercise of the mercy of God as a sovereign, and of his strict justice as a judge, agree together. And this is done by the sufferings of Christ, in which sin is punished fully, and justice answered. Christ suffered enough for the punishment of the sins of the greatest sinner that ever lived. So that God, when he judges, may act according to a rule of strict justice, and yet acquit the sinner, if he be in Christ. Justice cannot require any more for any man’s sins, than those sufferings of one of the persons in the Trinity, which Christ suffered. Romans 3:25,26. “Whom God hath set forth to be a propitiation through faith in his blood; to declare his righteousness, that he might be just, and the justifier of him which believeth in Christ.”
