Since God and Messiah are united in their work, the “Spirit of God” and the “Spirit of Christ” (Rom. 8:9) are one and the same (cf. Eph. 4:3–5). Those who know Messiah, know God, and vice versa (cf. John 8:19; 12:44– 50; 14:7–11). And those who follow Messiah, follow God, and vice versa (cf. Matt. 10:32–33; 16:23–27). So those who become disciples by repenting at the preaching of the day of the Lord (cf. Matt. 28:18) are commanded to be baptized “in the name of the Father and of the Son and of the Holy Spirit” (v. 19)—the Father will judge and restore creation through his Son by the power of his Spirit. -John P. Harrigan, The Gospel of Christ Crucified, p.123
