Adam blamed Eve. Eve blamed Satan. Satan Blamed God.
God took the blame upon Himself to claim a fallen race of people and end the war that started in Heaven.
Why Did Jesus have to be perfect and Die?
Because God has set up a LAW.. Kind of like our government today, and the Law states that if you SIN you MUST die.. There is NO way around the law.
Something MUST die for that sin because GOD's law DEMANDS it..
Satan was the first sinner, God made the laws on earth because(I'm speculating) there were no laws in heaven sentencing someone to death for sinning, because sin wasn't even ALIVE..
Satan now comes to earth where he knows that God is creating brand new SINLESS creatures.. His master plan was to make ADAM and EVE eat from the tree of knowledge of Good and Evil, and then Eat from the tree of life.. This would open the way for sin to remain IMMORTAL in the Universe.. How aweful!!
Next we know that God banishes Adam and Eve from the Garden so they won't become immortal sinners.. He knows how aweful and full of disgusting practices people are so he makes the earth anew again so he can put his plan into action..
After the flood God establishes the way he wants his government to be run on Earth.. God sets up the EXACT LAWS that govern himself.. GOD CANNOT break this laws because he IS this Law..
The law in essence is a perfect replica of 2 things..
#1 it shows in fullness the purity and Character of God.
#2 it forshadows the death on the cross and the atonement by Jesus..
Here is the reason that Jesus needs to be sinless.
In times before Jesus was made human, man could offer up for a sacrifice a lamb.. The lamb represented Jesus. This was a SUBSTITUTE.. The Lamb is considered a life JUST the same a human for reasons they are BOTH made by Jesus..
Jesus COULD NOT OFFER A LAMB!
Why?? Because a lamb is the work of Jesus' hands. It would be like a human offering a birdhouse, rather than a lamb..
Since Jesus created EVERYTHING... What is there left for him to sacrifice?? He is EVERYTHING.. So he must GIVE everything.. Jesus must give Himself for the eradication of Sin.. There is NO other way..
If Jesus had any Sin in him for ANY reason, he would not be an able substitute. Because how can you ATONE FOR SINS when you HAVE sin. Jesus would be under the LAW and the same condemnation as everyone Else. His earthly Body would die, He would not have accomplished ANYTHYING, but would have lost EVERYTHING.. This was a ONE TIME ONLY chance.. Since Jesus is only one being he could not try over and over again until he was perfect.
He must succeed the First time, or else GIVE CONTROL of planet earth to Satan.. Who in JOB chapter one, claims to be the ruler of earth anyways.
Thank God Jesus never lost control.
