John 3:17

For God sent not, etc. - It was the opinion of the Jews that the Gentiles, whom they often term the world, עלמה olmah, and אומות העולם omoth haolam, nations of the world, were to be destroyed in the days of the Messiah. Christ corrects this false opinion; and teaches here a contrary doctrine. God, by giving his Son, and publishing his design in giving him, shows that he purposes the salvation, not the destruction, of the world - the Gentile people: nevertheless, those who will not receive the salvation he had provided for them, whether Jews or Gentiles, must necessarily perish; for this plain reason, There is but one remedy, and they refuse to apply it.

To condemn the world - Not to judge, or pronounce sentence on mankind. God might justly have sent him for this. Man deserved condemnation, and it would have been right to have pronounced it; but God was willing that there should be an offer of pardon, and the sentence of condemnation was delayed. But, although Jesus did not come then to condemn mankind, yet the time is coming when he will return to judge the living and the dead, Acts 17:31; 2 Corinthians 5:10; Matthew 25:31-46.

3:17 God sent not his Son into the world to condemn the world - Although many accuse him of it.
