So many believers erroneously keep referring to themselves as Gentiles. They've never realized that they're no longer "Gentile" once they have accepted the God of Abraham, Isaac and Jacob!
They have become "Hebrew" and thus, a part of Israel - God's CHOSEN - and here's why:
Remember how YHWH told Abram (the pagan Chaldean who accepted YHWH as his ELOHIM) "to cross over" into the land which YHWH commanded him to head to, in Genesis 12?
Well, once he crossed over (both physically and spiritually), he became a "Hebrew" - a word that means, "to cross over!" Abram as you know, became our first forefather, and was renamed Abraham (a name that translates to "Father of a multitude).
This also means that YOU "become a Hebrew" once you have accepted YHWH as your God and His Divine Son whose shed blood removed your past sins! (John 14:6)
Now, note what YHWH commanded His people to do just before they FINALLY got to enter the Promised Land of Israel:
Deuteronomy 11: 30 Both are west of the Yarden, in the direction of the sunset, in the land of the Kena'ani living in the 'Aravah, across from Gilgal, near the pistachio trees of Moreh. 31 For you are to cross the Yarden to enter and take possession of the land ADONAI your God is giving you; you are to own it and live in it. 32 And you are to take care to follow all the laws and rulings I am setting before you today. (CJB)
Note the words, "you are to cross" in verse 31, followed by a warning to FOLLOW ALL THE LAWS AND RULINGS they've learned over the last 40 years....
Once we "cross over" we MUST obey His Divine Instructions in Righteousness, IF we want all to "go well with us." (See Exodus 15:26, Deuteronomy 6:3 and 12:28, Jeremiah 7:23, and a whole host of other passages.) YHWH reiterated that over and over again, throughout the entire Torah - as did Yeshua and his Apostles in the Renewed Covenant!
Notice what I said above? Once WE "cross over?" .... Yup - same God, same rules....(See Exodus 12:49, Numbers 15:13-16, Isaiah 56:6, Galatians 3:28 and Romans 10:12-13.)
