What does your baptism mean?
“[B]aptism signifies union with Christ in the virtue of his death and the power of his resurrection, purification from the defilement of sin by the renewing grace of the Holy Spirit, and purification from the guilt of sin by the sprinkling of the blood of Christ. The emphasis must be placed, however, upon union with Christ. It is this that is central, and it is this notion that appears more explicitly and pervasively than any other. Hence our view of baptism must be governed by this concept.” (John Murray, Christian Baptism, p. 8).
“Paul will argue that in this Son, the sons of God are neither male nor female, all are one in the one Son. The selection of ‘son’ (huios) or ‘sons’ (huioi) serves Paul’s purpose to expose the inviolable, indissoluble filial solidarity of the redeemed with the Redeemer. Just as the Pauline label of the church as the bride of Christ (Eph. 5:21–32) does not exclude males, the choice of huios does not eliminate or alienate believing females,who are also the sons of God.” (David B. Gardner, Sons in the Son: The Riches and Reach of Adoption in Christ, p. 53).
“For as many as were baptized into Christ, into fellowship with him, have put on Christ, appropriating Christ, so that now they are in Christ and belong to him (Gal. 3:27–29),walk in newness of life (Rom. 6:4, 6ff.; Eph. 5:26), live to God (Rom. 6:11, 13), and indeed carry the life of Christ within themselves (Gal. 2:20). And just as by baptism they entered into communion with Christ, so they also entered into fellowship with his church, which is his body.” (Herman Bavinck, Reformed Dogmatics, Vol. 4, p. 505).
