Hebrews 9:26-30

Otherwise, He would have needed to suffer often since the foundation of the world; but now once at the consummation of the ages He has been revealed to put away sin by the sacrifice of Himself.

And just as it is destined for people to die once, and after this comes judgment,

so Christ also, having been offered once to bear the sins of many, will appear a second time for salvation without reference to sin, to those who eagerly await Him.
