Galatians 4:5

4:5 to redeem those who were under the law, so that we may be adopted as sons with full rights. ¹ 

Romans 6:14-15

6:14 For sin will have no mastery over you, because you are not under law but under grace.

The Believer’s Enslavement to God’s Righteousness

6:15 What then? Shall we sin because we are not under law but under grace? Absolutely not!

¹ tn The Greek term υἱοθεσία (Juioqesia) was originally a legal technical term for adoption as a son with full rights of inheritance. BDAG 1024 s.v. notes, “a legal t.t. of ‘adoption’ of children, in our lit., i.e. in Paul, only in a transferred sense of a transcendent filial relationship between God and humans (with the legal aspect, not gender specificity, as major semantic component).” Although some modern translations remove the filial sense completely and render the term merely “adoption” (cf. NAB), the retention of this component of meaning was accomplished in the present translation by the phrase “as sons.”
