Jesus warned that God would condemn those who rejected his message.

John 12:44-50

44 Another day, when Jesus was teaching the people, he shouted, “Those who believe in me, they are not believing in me alone. Instead, it is as though they also believe in the one who sent me. 45 When they see me and what I am doing, it is as though they are seeing the one who sent me. 46 I have come into the world to show people God’s truth, as a light shows people what is around them. I have come in order that people who believe in me will not remain ignorant of God’s truth [MET], as those who are in the darkness are ignorant of what is around them.

47 As for those who hear my message but do not obey its commands, I am not the one who judges them. The main reason that I came ◄into the world/from heaven► was not to judge the people of [MTY] the world. Instead, I came to save them from being punished for their sins. 48 There is something that will judge those who reject me and do not accept my message. On the judgment day God will condemn them because they rejected the message that I have told them. 49 I have not said things from my own authority. Instead, my Father, the one who sent me, instructed me what to say and how I should say it. 50 I know that paying attention to what he has instructed us leads to eternal life. So whatever I say is exactly (OR, only) what my Father has told me to say.”
