'Heirs' in the Bible

In Him we Jews have been made heirs, having been chosen beforehand in accordance with the intention of Him whose might carries out in everything the design of His own will,

Among these [unbelievers] we all once lived in the passions of our flesh [our behavior governed by the sinful self], indulging the desires of human nature [without the Holy Spirit] and [the impulses] of the [sinful] mind. We were, by nature, children [under the sentence] of [God’s] wrath, just like the rest [of mankind].

The Gentiles are coheirs, members of the same body, and partners of the promise in Christ Jesus through the gospel.
