Bible Verses About The Atonement: Made but once

For the Messiah has entered a Holiest Place which is not man-made and merely a copy of the true one, but into heaven itself, in order to appear now on our behalf in the very presence of God.

Further, he did not enter heaven to offer himself over and over again, like the cohen hagadol who enters the Holiest Place year after year with blood that is not his own;

for then he would have had to suffer death many times — from the founding of the universe on. But as it is, he has appeared once at the end of the ages in order to do away with sin through the sacrifice of himself.

Just as human beings have to die once, but after this comes judgment,

so also the Messiah, having been offered once to bear the sins of many, will appear a second time, not to deal with sin, but to deliver those who are eagerly waiting for him.
