Hebrews 9:26-28

Otherwise, he would need to have suffered repeatedly since the beginning of the world. But now, one time, at the consummation of the ages, he has appeared in order to destroy sin though his own sacrifice. And in the same manner as it has been appointed for men to die one time, and after this, to be judged, so also Christ was offered, one time, in order to empty the sins of so many. He shall appear a second time without sin, for those who await him, unto salvation.
