A collection of scripture (English Standard Version) referring to Christ followers as family.
These words are all used in scripture, with approximately the same meanings.
But to all who did receive [Jesus], who believed in his name, he gave the right to become children of God, who were born, not of blood nor of the will of the flesh nor of the will of [people], but of God.
EPHESIANS 2:19-22 & 5:1
So then you are no longer strangers and aliens, but you are fellow citizens with the saints and members of the household of God, built on the foundation of the apostles and prophets, Christ Jesus himself being the cornerstone, in whom the whole structure, being joined together, grows into a holy temple in the Lord. In him you also are being built together into a dwelling place for God by the Spirit.
Therefore be imitators of God, as beloved children.
GALATIANS 3:26 & 6:10
For in Christ Jesus you are all children of God, through faith.
So then, as we have opportunity, let us do good to everyone, and especially to those who are of
the household of faith.
14 Your offspring shall be like the dust of the earth, and you shall spread abroad to the west and to the east and to the north and to the south, and in you and your offspring shall all the families of the earth be blessed.
