27 Your baptism in Christ was not just washing you up for a fresh start. It also involved dressing you in an adult faith wardrobe - Christ's life, the fulfillment of God's original promise. 28 In Christ's family there can be no division into Jew and non-Jew, slave and free, male and female. Among us you are all equal. That is, we are all in a common relationship with Jesus Christ. 29 Also, since you are Christ's family, then you are Abraham's famous "descendant," heirs according to the covenant promises.

Commentary on Galatians 3:26-29
(Read Galatians 3:26-29)
Real Christians enjoy great privileges under the gospel; and are no longer accounted servants, but sons; not now kept at such a distance, and under such restraints as the Jews were. Having accepted Christ Jesus as their Lord and Saviour, and relying on him alone for justification and salvation, they become the sons of God. But no outward forms or profession can secure these blessings; for if any man have not the Spirit of Christ, he is none of his. In baptism we put on Christ; therein we profess to be his disciples. Being baptized into Christ, we are baptized into his death, that as he died and rose again, so we should die unto sin, and walk in newness and holiness of life. The putting on of Christ according to the gospel, consists not in outward imitation, but in a new birth, an entire change. He who makes believers to be heirs, will provide for them. Therefore our care must be to do the duties that belong to us, and all other cares we must cast upon God. And our special care must be for heaven; the things of this life are but trifles. The city of God in heaven, is the portion or child's part. Seek to be sure of that above all things.
