Notice how all three members of the Trinity are involved in Missions:
The Father is the first missionary, who goes out of himself in creating the world and sending the Son for our salvation. The Son is the second missionary, who redeems humanity and all creation through his life, death, resurrection and exaltation. The Holy Spirit is the third missionary, who creates and empowers the church, the fourth missionary, to go into the world.
Remember: God had only one Son.......and He was a Missionary!
