JESUS HAD TO COME TO CORRECT THIS ERROR BUT WITH A GRAVE SACRIFICE OF HIS OWN SELF ON THE CROSS TO SERVE AS PROPITIATION (Atoning sacrifice: To absolve (us) of wrongdoing, especially by standing as ,(our) equivalent.) FOR OUR SIN.

Due to this error, Satan usurp Adam's authority and became the god (Dominator) of this world (system).

God gave Adam a kingdom to have Dominion over but Adam traded this kingdom with a bite of the forbidden fruit and sold out to the Devil through his Disobedience.

The subject of Salvation has been misunderstood by many because many thought Jesus came to establish a religion (set of rules, beliefs, modes of reaching God etc). But in contrast, Jesus came to establish God's Kingdom.
