“Go therefore and make disciples of all the nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, Teaching them to observe all things that I have commanded you, and lo, I am with you always, even to the end of the age” (Matthew 28:19-20).
Having just declared that God had given Him all authority, Jesus here commands that His followers go into the world and make disciples in all nations by baptizing them.
Because of clear teaching in many other scriptures, we know by command and example that baptism is immersion, a process in which a person is completely submerged under water.
A second part of the command is “Teaching”—that is, the process does not stop with baptism. Those who have been baptized must be given instruction about all other commands in scripture, including acceptable worship and living a pure, moral life. The goal is to submit to Jesus’ word in this life so that we can reap the reward in the next.
