The Bible makes it clear that Israel was in a unique relationship with God that did not pertain to Gentiles at all. That relationship involved: (1) the land of Israel; (2) the Law of Moses; and (3) that the Messiah would reign over Israel on the throne of David. None of these pertained to Gentiles (Leviticus:20:24–26, Psalm:147:19–20, etc.), nor do they pertain to the church, which is a new entity composed of both Jews and Gentiles who have a different relationship with God through Jesus Christ not based upon the Mosaic law. God’s saving grace does not turn Gentiles into Jews, but makes of both a new man (Galatians:3:23–29, Ephesians:2:11–22).
"Brethren, my heart’s desire and prayer to God for Israel is, that they might be saved."
