For I affirm Christ to have become a minister of circumcision in behalf of the truth of God, - to confirm the promises of the fathers,

The Spirit himself confirms to our spirit that we are children of God,

Do we then through faith make null and void the law? Not at all; instead, we confirm it.

He received the sign of circumcision as a seal [confirming] that he had been [considered] righteous because of the faith he had before being circumcised. Thus, he became the [spiritual] father of all people who believe [in God], even though they have not been circumcised, so that they could be considered righteous [by their faith].

I am telling [you] the truth in Christ [i.e., since I am a Christian]; I am not lying. My conscience, [confirmed] by the Holy Spirit, supports my statements [as true],

"But if our unrighteousness confirm the righteousness of God, what shall we say? Is not God unrighteous, who inflicteth his wrath?" (I speak as a man) God forbid:

And to him that is able to confirm you according to my gospel, and the preaching of Jesus Christ, according to the revelation of the mystery not revealed in ancient times,

and though the children were still unborn and had done nothing either good or bad (to confirm the divine purpose in election which depends upon the call of God, not on anything man does),

For with the heart a person believes [in Christ as Savior] resulting in his justification [that is, being made righteous—being freed of the guilt of sin and made acceptable to God]; and with the mouth he acknowledges and confesses [his faith openly], resulting in and confirming [his] salvation.
