Warren draws the connection through Isaiah’s vision: when Isaiah encountered God’s holiness (chapter 6), the immediate result was “Here am I, send me!” Authentic worship produces evangelistic urgency as its natural fruit. You cannot genuinely encounter the living God and have nothing to say about it.
The feedback loop runs in both directions. Evangelism’s goal is to produce worshipers — people who come to know God and orient their lives toward him. Those worshipers then encounter God more deeply, which compels them outward again. The two are not competing priorities but a single spiral.
This reframes the tension churches feel between “deep formation” and “seeker accessibility.” The tension is real in the short run — you can’t be equally optimized for both in a single service. But in the longer arc, they are not in competition. A community that worships deeply will want to bring people into that encounter. A community that evangelizes faithfully will produce worshipers who deepen the community’s worship life.
For MNFC, this suggests a diagnostic: if Sunday services are focused on evangelism but members’ private worship life is thin, the outreach won’t have fuel. Conversely, if members are well-formed devotionally but Sunday never speaks to the unchurched, the formation is turning inward. The health indicator is whether both flows are active simultaneously.
Warren’s corollary: changed lives — actual visible transformation — are the best evangelism. That requires genuine shimjeong-filled worship producing genuine change in the community.
