Matthew 28:19

Go, then, to all peoples. This officially revokes the "limited mission" to the Jews. From this time on, they are to go to all peoples (which includes the Jews). And make them my disciples. Their mission is to "MAKE DISCIPLES" for Christ (which includes "salvation"). They are to declare the facts about Jesus (1 Corinthians 15:1-4; Acts 17:18), so that people will become followers of Jesus and use his principles to guide their lives. Baptize them. The rite by which followers of Jesus are to be "initiated" into Christ and "united" with him. See Colossians 2:12; 1 Peter 3:21. In the name of the Father, the Son, and the Holy Spirit. Not "the names," but "THE NAME" stressing the Triune nature of God. Alford says it speaks to an "objective admission into the covenant of Redemption." The initiation which Christ commands here is "of water and the Spirit" (John 3:5) and is the "washing by which the Holy Spirit gives us new birth and new life" (Titus 3:4-5). [This is no deficient initiation. It is as much the baptism of the Holy Spirit as it is the baptism of Christ as it is the baptism of the Father. There is one [Christian] baptism of water and the Holy Spirit. Either one is a Spirit-filled Christian or he is not a Christian at all (Romans 8:9). The Triune God is indivisibly ONE.] In this rite of initiation, The Father welcomes the believer as a child; the Son welcomes the believer as a brother [sister]; by the Holy Spirit's power, we cry to God, "Father! my Father!" (Romans 8:15).
