Our church leaders "learned" in the 1950s that the purpose for assemblies is to "worship correctly", which puts the focus on singing right and preaching the right message and doing the Lord's Supper right and controlling who can say what when and all these "regulations", which have the appearance of wise worship.
There's nothing wrong with these things, but that's not what our leaders should focus on. Our leaders were given to us for a different purpose:
WEB Eph 4:[11 ]He gave some to be apostles; and some, prophets; and some, evangelists; and some, shepherds and teachers; [12 ]for the perfecting of the saints, to the work of serving, to the building up of the body of Christ...
If you're a church leader, and you're not helping your sheep mature to the point of serving and building, you're not doing your job.
Your purpose is not to conduct a "God-pleasing worship service". Your purpose is to conduct a personal-growth seminar.
Paul writes this same message elsewhere:
WEB 1 Cor 14:[26 ]What is it then, brothers? When you come together, each one of you has a psalm, has a teaching, has a revelation, has another language, has an interpretation. Let all things be done to build each other up.
It's about training each member of the flock to develop and use his own God-given gifts, whatever those gifts are, to be used in the service of God's kingdom.
Can you imagine the difference we'd make in the world if we were producing armies of men and women trained to use their skill-sets in the work of the kingdom? Medical researchers giving sight to the blind. Lawyers defending the rights of the oppressed. Film-makers drawing in block-buster crowds to be influenced to no longer steal but to work productive lives. Business managers who keep the books honestly. Employers who "do right" by their employees. Engineers who develop life-enhancing products cheap enough for third-world countries. Farmers who feed the starving. Spiritual advisors who pray in Jesus' name with their clients. Public speakers who inspire listeners to make the right choices in life. Power-point developers who make God's message vibrant and alive. Software programmers who hide God-honoring easter eggs in their work. Singers who put the Norman Fishing-Tackle Choir to shame. People who make a difference in the world, because their God-given talents were developed by godly leaders who have learned to recognize and nurture those talents in each individual.
From Jesus' first public sermon:
KJV Luke 4:[18 ] The Spirit of the Lord is upon me, because he hath anointed me to preach the gospel to the poor; he hath sent me to heal the brokenhearted, to preach deliverance to the captives, and recovering of sight to the blind, to set at liberty them that are bruised....
The assemblies are not about worship (although that does take place in the assembly). The assembly is about identifying and nurturing each one of us to do good works:
WEB Heb 10:[24 ]Let us consider how to provoke one another to love and good works, [25 ]not forsaking our own assembling together, as the custom of some is, but exhorting one another; and so much the more, as you see the Day approaching.
That may mean breaking away from our traditions of two songs, a prayer, a song, the Lord's Supper, a song, a sermon, an Invitation, contribution, and a closing hymn and prayer. It may mean breaking into small groups, learning how to place our hands on one another and praying as a group. It may mean setting aside time to ask each member, "What's happening in your life?", so we can get to know each other and each other's needs. It may mean spending less on the outdated bus program and sending a young Christian to medical school instead, who then cures cancer or provides doctoring to the congregation's been-there-a-year full-time members at an 80% discount for ten years after graduation. It may mean game-show style learning opportunities instead of 30-minute one-way sermons that are completely wasted on the post-MTV generation. It may mean adapting the assembly in whatever way is needed to develop 21st century Christians into 21st century kingdom powerhouses.
It starts with the leaders. Are you developing your flock according to their bent, or are you simply scratching your own itch to talk into a microphone?
