Missional is not as much a program as it is a focus or mindset. Taking its lead from the Father who sent the Son (John 20:21) and the Father and Son who sent the Holy Spirit (John 14:26, 15:26) and the Son who sends His followers (John 20:21), missional is focused on sending. It happens outside the church walls, where people live, work, shop and play. It is relational. Just as the three Persons of the Trinity are divinely relational, people were originally created in the image of God, and being relational is in our spiritual DNA. Therefore, relationships are vital to the work of the Lord among the people He loves. In fact, Lutherans celebrate, believe and teach that the grace of God is at work in the Sacraments, in His Word and in “the mutual conversation and consolation” of His people; it’s a very relational concept (Cf. Article IV of the Smalcald Articles).
Missional is also focused on the community. The Sacraments and the proclamation of the Word are largely celebrated within the walls of the church in the midst of God’s people; consolation and conversation happen in the market place, at soccer games, band practices, dance recitals, in the break room, at the café, even in the little corner market with Spanish posters advertising sales on vegetables.
