Since the 2000s, both the public credibility of the Korean
church and the quantitative growth of the church have
been steadily declining. Under these circumstancessermons
in the Korean church still emphasize the daily and private
lives of believers rather than addressing their responsibilities
as saved people the role of the faith community in changing
times. However, sermons inevitably public and address the
responsibilities and missions in the public sphere that God
has entrusted to believers and the church. This paper
examine the reasons why the Korean church has lost the
public nature of preaching and discuss the urgency of
restoring the public nature of preaching. In addition, will
discuss the priority of establishing the identity of believers
and the church as a way to restore the publicity of preaching,
and propose a sermon based on the narrative of
redemptive history as a homiletical alternative for
establishing the identity of believers and the church.
