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 4:7

For who makes you different [from each other]? [i.e., with some being viewed as superior and others inferior]. And what do you have that you did not receive [from God]? But if you received it [from Him], then why do you boast as though you did not [receive it as a gift]?

Titus 3:3-5

For we [Christians] were also once foolish, disobedient, deceived, enslaved to various kinds of [evil] desires and [sinful] pleasures. [We used to] live in malice and envy, hating people and being hated by them.
