Christian Judgment

Elder Gaul:

[27] And as it is appointed unto men once to die, but after this the judgment:

AND

[22] And almost all things are by the law purged with blood; and without shedding of blood is no remission.

Sir, WHY is there no remission without shedding of blood?

Since judgment comes AFTER death, the shedding of human blood
is especially to be studied. Christians believe that Jesus'
blood was actually shed like that of a sacrificial lamb. So
whether it is lamb's blood or human blood, it seems to work
for the "remission [of sins]." Why? Why do both human
and lamb's blood work for remission, and is this related
to the Powerful Almighty God and his Mosaic counterpart "I AM"?
