In the gospel of Matthew, the public ministry of Jesus opens and ends with baptism. In Matthew 3:13-17, Jesus came to John the Baptist to be baptized. In Jesus’ baptism, the Spirit of God descended upon him. With God the Father also confirming him as His Beloved Son, Jesus is therefore introduced for public ministry. Then in Matthew 28:19, after his resurrection and before Jesus ascended into heaven, he gave the great commission to his disciples, “Going (a literal translation) therefore, make disciples of all nations, baptizing them in the name of the Father, and of the Son, and of the Holy Spirit.” A close reading of his command allows us to see how important it is to Jesus that his disciples must make other disciples. And disciples precisely do this by (i) always being on the go, on the road as disciples and witnesses, and by (ii) continually baptizing all into communion with the Trinity – the Father, the Son, and the Holy Spirit.
