Hebrews 9:26

Ye know that he was manifested to take away our sins.—That we, being dead to sins, should live unto righteousness.—He is able also to save them to the uttermost that come unto God by him.

He was wounded for our transgressions, he was bruised for our iniquities: the chastisement of our peace was upon him; and with his stripes we are healed. The Lord hath laid on him the iniquity of us all.—Thus it behoved Christ to suffer, . . . that repentance and remission of sins should be preached in his name among all nations.—He appeared to put away sin by the sacrifice of himself.

The sting of death is sin.—But now once in the end of the world hath he appeared to put away sin by the sacrifice of himself.

And as it is appointed unto men once to die, but after this the judgment: so Christ was once offered to bear the sins of many; and unto them that look for him shall he appear the second time without sin unto salvation.

The Bible does not say that God punished the human race for one man's sin; but that the disposition of sin, viz., my claim to my right to myself, entered into the human race by one man, and that another Man took on Him the sin of the human race and put it away (Heb. 9:26) - an infinitely profounder revelation.

The disposition of sin is not immorality and wrong-doing, but the disposition of self-realization - I am my own god.
