Romans 11:18
Therefore, you should not brag [about your superiority] over the [natural] branches [i.e., the rejected Jews]. But, if you must brag, it should not be over you [Gentiles] nourishing the roots [i.e., the Jews], but over the roots nourishing you.
Matthew 26:33
Peter answered Him, "[Even] if everyone [else] has doubts about you, I never will."
Luke 18:9-11
Then Jesus told this parable to certain ones who were relying on their own goodness and putting everyone else down:
John 4:22
You [Samaritans] do not [really] know what you worship; we [Jews] know what we worship because salvation is from the Jews [i.e., through Jewish prophets, Jewish Scriptures and a Jewish Messiah].
John 10:16
I have other sheep [also] which are not [presently] in this corral; I must lead them, too. They will hear my voice and become one flock [i.e., with the others], having one shepherd. [Note: This probably refers to believing Gentiles becoming God's people, along with the Jews].
Romans 3:27
Where then is the [basis for] boasting [i.e., over being right with God]? There is not any. Is it by [obedience to] a law? Is it by doing certain deeds? Not at all, but by a law of faith.
Romans 4:16
For this reason, the promise [i.e., of being made right with God] comes through faith [in God], according to His unearned favor, so that it may be [given] with certainty to all of Abraham's descendants. The promise is given not only to those [who live] under the law [i.e., the Jews], but also to [all] those [who live] by faith, like Abraham. Abraham is the [spiritual] father of all of us [believers],
Romans 11:20
True, but they [i.e., the Jews] were [really] broken off because they did not believe [in Christ], and you [Gentiles] remain [in God's favor] because you do believe [in Him]. So, do not become arrogant [about it], but be fearful.
1 Corinthians 10:12
So, the person who thinks he is standing firm [in the faith] should pay attention [to his life], so that he does not fall [away from God].
Galatians 3:29
And if you belong to Christ, then you are [truly] Abraham's seed [i.e., his spiritual descendants] and thereby [you will] inherit what was promised to him [i.e., God's blessings].
Ephesians 2:19-20
So then, you [Gentiles] are no longer foreigners and aliens [i.e., to God's promises. See verse 12], but you are fellow-citizens with the saints [i.e., God's holy people], and are part of God's family.
