To understand the struggle that evangelicals have with worship you must first define it. Frankly, I think, like many things that we evangelicals struggle with, we have placed our focus on method, rather than purpose. When we argue over music and liturgy and all kinds of stuff “that happens” but what is underneath that, I think, is that we have lost the plot on the purpose of worship.
We have all heard the phrase, "the end justifies the means". It is a blanket rationale, when the ultimate outcome is worth any sacrifice, or expedience. It is used by governments to justify actions, and by good people to justify questionable actions.
How does fruit play into this? Well, the apostle Paul said "…I have become all things to all men, so that I may by all means save some." 1 Corinthians 9:22… What does this mean? This passage from 1 Cor 9:19-22 is all about fruit. It is about maintaining empathy for those that you are ministering to; about making sure our ministry remains relevant to those we are ministering to, so that we " by all means may save some." It is about ministry methods. How you conduct the ministry that you are engaged in. Because people get hung up on methods – specific ways of doing things that may engage some people, and turn others off. Again, it is about the fruit. God will bless methods that are aligned with His will by making them fruitful.
If we conduct ministry the way we did in 1970 or 1950 or even 1850, we probably will not get people engaged. Is it because those methods were not biblical? Probably not. Is it because people perceive them as archaic and out of date or step with "the times", most likely.
The bible doesn't really have a great prescription for how to conduct a church service, run a youth ministry; a women's program; a men's ministry. God left it up to us, each generation of believers to relate to our generation, our culture so that we would figure out how to cultivate the soil around us to produce fruit.
