'Father' in the Bible

[I am writing] to all who are beloved of God in Rome, called to be saints (God’s people) and set apart for a sanctified life, [that is, set apart for God and His purpose]: Grace to you and peace [inner calm and spiritual well-being] from God our Father and from the Lord Jesus Christ.

He received the sign of circumcision, a seal or confirmation of the righteousness which he had by faith while [he was still] uncircumcised—this was so that he would be the [spiritual] father of all who believe without being circumcised—so that righteousness would be credited to them,

and [that he would be] the [spiritual] father of those circumcised who are not only circumcised, but who also walk in the steps of the faith of our father Abraham which he had before he was circumcised.

Therefore, [inheriting] the promise depends entirely on faith [that is, confident trust in the unseen God], in order that it may be given as an act of grace [His unmerited favor and mercy], so that the promise will be [legally] guaranteed to all the descendants [of Abraham]—not only for those [Jewish believers] who keep the Law, but also for those [Gentile believers] who share the faith of Abraham, who is the [spiritual] father of us all—

(as it is written [in Scripture], “I have made you a father of many nations”) in the sight of Him in whom he believed, that is, God who gives life to the dead and calls into being that which does not exist.

In hope against hope Abraham believed that he would become a father of many nations, as he had been promised [by God]: “So [numberless] shall your descendants be.”

We have therefore been buried with Him through baptism into death, so that just as Christ was raised from the dead through the glory and power of the Father, we too might walk habitually in newness of life [abandoning our old ways].

For you have not received a spirit of slavery leading again to fear [of God’s judgment], but you have received the Spirit of adoption as sons [the Spirit producing sonship] by which we [joyfully] cry, “Abba! Father!”

so that with one accord you may with one voice glorify and praise and honor the God and Father of our Lord Jesus Christ.
