How do we know the Gospel is central to the church?

The centrality of the Gospel in the church is affirmed by Paul, who stresses that the church's identity hinges on the Gospel of Christ. In his exhortations to Timothy, Paul emphasizes remembering Jesus Christ and the Gospel, asserting that 'if there is no Gospel, there is no church' (2 Timothy 2:8). The Gospel is not merely a background theme; it is the heart of Christian faith and practice. It is through the Gospel that individuals are saved, transformed, and called to a life of obedience and service. Thus, the health of the church is deeply connected to its faithfulness in preaching and living out the Gospel.
