28:19 go and: Literally going, a participle that supports the main imperative, make disciples. Matthew probably intended go to be understood as a separate command (as it is translated) and not as a circumstantial modifier (i.e., while you go; cp. the same construction in 9:6; Acts 10:20). • make disciples: A disciple is one who repents of sin, trusts in Jesus for salvation, and obeys his teachings. • all the nations: The mission to the Gentile nations formally began here (see Matt 10:5-6; 15:24; see also 1:1; 2:1-12; 8:5-13; 21:43; 24:14; 26:13). • Two aspects of making disciples are baptizing and teaching (28:20).. Baptism indicates public identification with, and surrender to, Jesus and the work he has done for salvation (see 3:13-17; 10:32-33; 20:28; 26:28; Acts 2:38; Rom 6:1-11; 1 Pet 3:21). • In the name of means entrance into a relationship and its benefits, which come to those who truly believe. • Father . . . Son . . . Holy Spirit: This is a formulaic expression for the nature of God as a trinity (see also 1 Cor 12:4-6; 2 Cor 13:14; Eph 4:4-6; 2 Thes 2:13-14; 1 Pet 1:2; Rev 1:4-6).
