I Paul, am saying all this especially for you Gentiles. (believers in Christ) God has appointed me as the apostle to the Gentiles. I stress this, for I want somehow to make the people of Israel jealous of what.... "YOU GENTILES HAVE," (faith in Christ) so I might save some of them.
 
Some of these branches from Abraham’s tree—some of the people of Israel—have been broken off. And YOU Gentiles, who were branches from a wild olive tree, have been grafted "IN." So now YOU also "RECEIVE THE BLESSING" God has promised Abraham and His children, sharing in the rich nourishment from the root of God’s special olive tree.

BUT... YOU must not brag about being (saved) grafted.... "IN" to replace the branches that were broken off. You are just a branch, (attached to Christ) not the root.

“Well,” YOU MAY SAY, “those branches were broken off to make room for me.” (I'm in - SAVED)
 YES, BUT.....remember—those branches were broken off... BECAUSE.... THEY DID NOT BELIEVE IN CHRIST, and "YOU are there"... BECAUSE... YOU do believe in Christ.
 
So don’t think highly of yourself, BUT........ "FEAR WHAT COULD HAPPEN."
 
For if God did not spare the original branches (who did not believe), HE WILL NOT SPARE YOU EITHER. (WHO DO BELIEVE)

NOTICE (NOW) HOW....God is both kind and severe. He is severe toward those who disobeyed, BUT KIND TO YOU...... IF YOU CONTINUE.... to trust in His kindness.
 
BUT IF.....YOU STOP TRUSTING (In Christ), YOU (BELIEVER) WILL ALSO BE CUT OFF. (Romans 11:13,14,17-22)

***Never forget God is always ...Holy, Holy, Holy, and always... Completely Just.
