The Old Testament Law.
The New Testament Law.
Under the old covenant GOD commanded,keep the law but JESUS had not yet come to earth and because of the weakness of the flesh under the old covenant they could not be perfect before GOD.
Under law,they were sacrificing the blood of Innocent lambs to temporarily be cleaned.
They would press their hands,transferring their sin Into the lamb.
Only by
grace through faith could we be perfect before GOD.
In the new testament JESUS was the lamb of GOD that
took away the sins of the world.
Someone might ask,If JESUS took away the sins of the world,then why Is sin still here?
JESUS said that the words he spoke were Spirit and they are Life.
Only GOD can make the spirit clean and we have access to this grace through faith.
