In Galatians Paul's Jewish-Christian opponents emphasized the importance of being physically related to Abraham. But Paul answered them by saying in Christ every Christian is viewed by God as a descendent of Abraham.
27 For all of you who were immersed into Christ have clothed yourselves with Christ.
28 There is neither Jew nor Greek, there is neither slave nor free man, there is neither male nor female; for you are all one in Christ Jesus.
29 And if you belong to Christ, then you are Abraham's offspring, heirs according to promise—(Gal 3:27-29).
Since believers are all one in Christ Jesus, and they belong to Christ and are clothed in him, Christ’s direct descent from Abraham is also counted to be true of us. And if we are descendants of Abraham, we are also heirs to Abraham’s promised blessings. Everything we need for full acceptance from God is ours. The false teachers in Galatians were telling the Christians they needed more, but Paul was telling those same Christians they had in Christ all that they needed. You are not needy. You are blessed beyond measure.
