Job knew about salvation. (Job 14:14-15)
Job knew to please God.
What does God tell us to do now?
God tells us to obey Jesus.
The shadow was circumcision; the observance of special days, including the Sabbath day;; adherence to a dietary law, various external washings, and the sacrifice of animals.
THOSE WORKS ARE NO MORE FOR EVERYONE. There is NO MORE SEPARATION between JEW AND GENTILE.
WE were ALL BOUND TO THE SAME PLACE, the place of disobedience.
The dividing wall was destroyed.
The dividing wall was the ceremonial/purification works the Jews USED TO HAVE TO DO, but the Gentiles were UN clean because they did not do those works. They could have converted and did those works, but they did not.
No one has to do those WORKS anymore, for those things NO LONGER are used to teach one how to clean themselves, for the shadows are gone, because Jesus Christ came. When the light shines behind a man, it casts a shadow before the man. Jesus is the light, and in him there are no shadows. HE MAKES US CLEAN, by our only having to have FAITH that his blood cleans us. That means we no longer have to clean ourselves first by watching our diet, getting circumcised, and sacrificing animals, etc.
We still have to obey Jesus, but not clean ourselves by THOSE WORKS.
