If a true believer could fully and finally fall away, what it would mean for God the Holy Spirit? 1. The Holy Spirit will have failed in his work of sealing (2 Cor. 1:21-22; Eph. 1:13-14; 4:30). 2. The Holy Spirit will have failed in his ministry as a pledge of the future consummation of our redemption (2 Cor. 1:21-22; 5:5). 3. The Spirit will have failed in his ministry as firstfruits (Rom. 8:23).
