A while back, John Armstrong wrote 3 terrific articles on how the Gospel of the Kingdom produces (or should produce!) missional followers.
People made in God’s image long for relationships. Having lost their relationship with God through sin they have lost all deeply satisfying relationships with their fellow human beings. All the unrest and social breakdown in the family and society is the result of this brokenness. But the gospel of the kingdom restores broken relationships, with both God and people.
Genuine loving relationships, in which trust and respect are central, are desired by all people. This is a part of that “God-shaped vacuum” we have heard about. And this is why the greatest apologetic of all is missional, or communal. People cannot function as they were made by God without relationships. This is why they gravitate to bars, civic clubs, college fraternities and sororities, sports teams, Gay Pride groups, Internet chat rooms and hundreds of other expressions of human community. And this is why the church fails to present the gospel of the kingdom effectively when it is ceases to be a unique community of people living eternal life in loving relationships.
The fullness of the kingdom of God must be preached and it must be demonstrated. This is not an either/or, but rather a both/and…. ….he great early church theologian Tertullian said this so well: “It is the Christian’s way of life that shows the validity of his beliefs: goodness is their identifying characteristic” (cited by William Dyrness, Christian Apologetics in a World Community, 28).
