Sons and Daughters in the Spirit
Unquestionably then, this new life that we live with the Father in Christ is founded exclusively on the work of the Spirit. The justification, focus, and ultimate culmination of this new life is comprised in the truth that through the indwelling of the Holy Spirit, received by faith and baptism, we have become sons and daughters of God. ‘For all who are led by the Spirit of God are sons of God. For you did not receive the spirit of slavery to fall back into fear, but you have received the spirit of sonship. When we cry, “Abba! Father!” it is the Spirit himself bearing witness with our spirit that we are children of God’ (Rom. 8:14-16). Similarly, in Galatians Paul writes: And because you are sons, God has sent the Spirit of his Son into our hearts, crying, “Abba! Father!” So through God you are no longer a slave but a son, and if a son then an heir’ (Gal. 4:6-7). Equally the splendor of the Spirit allows us to share in the splendor of the Lord so that ‘with unveiled Face, beholding the glory of the Lord, [we] are being changed into his likeness from one degree of glory to another; for this comes from the Lord who is the Spirit’ (2 Cor. 4:7-18).
