I am enjoying the current issue of Themelios. The article Do The Work of an Evangelist by D.A. Carson is truly excellent. It ties closely to the main theme of Armchair Theology so here is an excerpt with my commentary.
For some Christians, “the gospel” (equivalently, “the evangel”) is something you preach only to unconverted people. The gospel merely tips people into the kingdom; transformation and sanctification are sustained by discipleship. Once people become Christians, then the work of life transformation begins, often buttressed by various discipleship seminars: “Biblical Leadership,” “Learning to Pray,” “What to Do with Your Money,” “Christian Marriage,” and so forth—none of which falls under “gospel,” but only under post-gospel discipleship.
One of my main goals is to see the gospel applied to all life – especially growth in holiness:
In recent years, however, many preachers and theologians have convincingly argued that “gospel”/“evangel” is the larger category under which both evangelism and discipleship fall. In the NT, gospel is not everything—it is not law, for instance—but it is a very big thing, precisely because it is the unimaginably great news about what God is doing in and through King Jesus, especially in and through his cross and resurrection. A careful reading of Scripture shows how often Christian conduct is grounded in the gospel itself.
This was a game-changer for me a few years ago. Every time we see a command in the Bible it is prefaced with the gospel message. This isn’t limited to just the New Testament. Read Ex 20:2 and see how the ten commandments are prefaced with a message of God’s saving work for his people.
For instance, the gospel is to be obeyed (e.g., 2 Thess 1:8); certain behavior conforms to the gospel, while other behavior does not (1 Tim 1:10–11). Husbands are to love their wives as Christ loved the church and gave himself up for her (Eph 5:25)—transparently, this is a gospel appeal. In short, in the NT the gospel is preached both to unbelievers and to believers. It calls unbelievers to repentance and faith; it calls believers to ongoing faith and conformity to Jesus.
Gospel ministry is ministry that is faithful to the gospel, that announces the gospel and applies the gospel and encourages people to believe the gospel and thus live out the gospel.
