Obviously, this mentality and focus has far-reaching implications on all areas of life, like family, work, and church, but what he says about how a missional focus ought to impact a church's worship style is worth noting. Here's what he says...
I am proposing that missiology come into prominence, both as a theological pursuit and as a guiding operational paradigm. Even the issues that have captured the church’s attention should be framed against the backdrop or under the overarching theme of missiology. For instance, the discussion of worship unfortunately often occurs without a missiological perspective. Witness the church worship wars. These are the result of club members discussing their worship style preferences as stockholders and stake holders, not as missionaries.This "missional" perspective must be included in the discussion of what music should be played on a Sunday morning during the worship service. The worship music cannot just be targeted toward the likes and preferences of the "club members." We must take into consideration the evangelistic power of the songs we sing.
The usual goal is to find something that club members like. We’ve all heard discussions among church leaders involving questions such as, “Can nonbelievers really worship God?” or “Should our worship be seeker-sensitive or seeker-driven?” as though worship is not a powerful evangelistic tool to express the church’s mission in the world! Nonbelievers are already worshiping, because people are built to worship something. Our challenge is to upgrade their worship to worship of the true God.
On any given Sunday, there are scores of people that attend churches all across America who have not placed their faith and trust in Christ. These are not just the random people who stop in one Sunday a year, but these are also people who attend church every week and faithfully serve. As church leaders consider what songs to sing, what prayers to pray, and what sermons to preach, this reality must be taken into consideration.
Some may call this approach "seeker-sensitive" and may react negatively to it. But if we understand that God has called us to live like missionaries 24/7 among our neighbors, co-workers, family members and friends, then making sure that even our Sunday morning worship service has a missional flavor to it is essential.
