Hebrews 9:25-26

25The leader of the priests here on earth goes into the Most Holy Place every year. Each time, he takes with him the blood of an animal and he offers it to God. But when Christ went into heaven to offer himself to God, he did not do that again and again.

26To do that, he would need to die again and again, many times since the world began. No! Christ has appeared just once. He has appeared now, when time is near its end. He came and he died as a sacrifice. In that way, he has removed the power of sin.
