The World Through Him Might Be Saved
For God did not send His Son into the world to condemn the world, but that the world through Him might be saved. John 3:17 NKJV
Here is God's design in sending hi Son into the world: it was that the world through him might be saved. He came into the world with salvation in his eye, with salvation in his hand. Therefore the aforementioned offer of live and salvation is sincere, and shall be made good to all that by faith accept it.
God sent his Son into the world, this guilty, rebellious, apostate world sent him as his agent or ambassador, not as sometimes he had sent angels into the world as visitants, but as resident. Ever since man sinned, he has dreaded the approach and appearance of any special messenger from heaven, as being conscious of guilt and looking for judgment: We shall surely die, for we have seen God. If therefore the Son of God himself come, we are concerned to inquire on what errand he comes: Is it peace? Or, as they asked Samuel trembling, Comest thou peaceably? And this scripture returns the answer, Peaceably.
He did not come to condemn the world. We had reason enough to expect that he should, for it is a guilty world it is convicted, and what cause can be shown why judgment should not be given, and execution awarded, according to law? That one blood of which all nations of men are made (Acts 17:26) is not only tainted with an hereditary disease, like Gehazi's leprosy, but it is tainted with an hereditary guilt, like that of the Amalekites, with whom God had war from generation to generation and justly may such a world as this be condemned and if God would have sent to condemn it he had angels at command, to pour out the vials of his wrath, a cherub with a flaming sword ready to do execution. If the Lord had been pleased to kill us, he would not have sent his Son amongst us. He came with full powers indeed to execute judgment (John 5:22,27), but did not begin with a judgment of condemnation, did not proceed upon the outlawry, nor take advantage against us for the breach of the covenant of innocency, but put us upon a new trial before a throne of grace.
He came that the world through him might be saved, that a door of salvation might be opened to the world, and whoever would might enter in by it. God was in Christ reconciling the world to himself, and so saving it. An act of indemnity is passed and published, through Christ a remedial law made, and the world of mankind dealt with, not according to the rigours of the first covenant, but according to the riches of the second that the world through him might be saved, for it could never be saved but through him there is not salvation in any other. This is good news to a convinced conscience, healing to broken bones and bleeding wounds, that Christ, our judge, came not to condemn, but to save. - Matthew Henry
