Missio Dei: The God Who Is On Mission
I don't think that people always understand the biblical idea of mission.
The Heavenly Father isn’t just affirming a mission—He is on mission. Jesus affirmed, “As the Father has sent me, so I am sending you” (John 20:21b).
The term Missio Dei is a Latin term meaning "the sending of God."
This idea of the Missio Dei is on display in the interrelationship of the Trinity. God the Father sends the Son, and God the Father and the Son sends the Spirit.
We know that the gospel is the result of God’s initiative—rooted in His purposes to restore and heal creation. However, in the midst of unfolding glory, the Lord is graciously inviting us to join Him in His work.
The European theologian Jurgen Moltmann wrote, "It is not the church that has a mission of salvation to fulfill in the world; it is the mission of the Son and the Spirit through the Father that includes the church." 
We must never forget that the gospel is good news from a good God on a good mission. Any understanding that is not grounded in this truth will miss the meaning and scope of the Kingdom of God.
