19 Go therefore and make disciples of all nations
The real verb in the Great Commission is “make”(Matt 28:19). Technically, while “go” is a command, it is a participle in the Greek. It is not the main verb or thrust of the sentence.
The point is that as we are going (i.e. going through our day) we are to be involved in disciple making: teaching people to follow Jesus.
Who are you actively discipling?
