TLDR: Sup. The OT has Gentiles and sometimes nations turning to God and being accepted. Disproving the common misconception of “ethnicity based salvation”. Hey everyone, I hope you are doing well. I wanted to share something which took a while for me to be able to notice; And that I feel is not a common point people bring up nowadays. That is, the indications from the Old testament of a future fulfillment of the ingrafting of the Gentiles. Of course, there are New Testament cross references too ; But hopefully I am also able to share with you some more that may not have been noticed. In the New Testament we find it finally clear as day in Acts 11:18, and repeatedly throughout the Epistles we can see that Gods inheritance (Israel) is no longer mis-conceptualized as having a pre-requisite simply based off ethnicity, but rather, faith that ingrafts to the promise made to Abraham (Genesis 26:4 & Galatians 3:24) . This concept was not foreign and most certainly was not new. My first point should be concerning the logic behind it, that is, God is God over all the earth; Why shouldn’t it be then that He is also the God that everyone comes to believe in? Isaiah 45:22-23 (Look unto me, and be ye saved, all the ends of the earth: for I am God, and there is none else. I have sworn by myself, the word is gone out of my mouth in righteousness, and shall not return, That unto me every knee shall bow, every tongue shall swear). My second point will be that of Scriptural examples. (1) The first one that comes to mind is in Joshua 2, where Rahab the harlot hides two Israelite spies. Consequently she is accepted into the society of the Hebrews. Thus, her faith in the Lord was actualized in her work to helping the men. (Joshua 2:9 And she said unto the men, I know that the LORD hath given you the land). (Also see Hebrews 11:31, James 2:25). (2) Again in Jonah, do we see non Israelites receiving from God, what God initially gave to the Israelites; That being: Mercy. After Jonah's mission into Nineveh was completed, God sees their works produced by their faith in Him, and shows them mercy. Jonah is displeased at this but it is good in the eyes of the Lord.
