Hebrews 9:26-28

If Christ had offered himself many times, he would have needed to suffer many times since the time the world was made. But he came to offer himself only once. And that once is enough for all time. He came at a time when the world is nearing an end. He came to take away all sin by offering himself as a sacrifice. Everyone must die once. Then they are judged. So Christ was offered as a sacrifice one time to take away the sins of many people. And he will come a second time, but not to offer himself for sin. He will come the second time to bring salvation to those who are waiting for him.
