Since men only die once, and after that comes judgement, so Christ, too, offers himself only once to take the faults of many on himself, and when he appears a second time, it will not be to deal with sin but to reward with salvation those who are waiting for him.

For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. - John 3:16
