In my opinion, Sunday morning is not a good time for "Church." Ie, the gathering of the faithful in worship, fellowship, and teaching. Because of a few significant cultural shifts I have 2 reasons for moving our "Time" of corporate worship.
1) The world has changed.
Church attendance was almost mandatory in the United States 100 years ago. Most of the population went to some church. Even if segments of the population did not attend church, the world shut down on Sundays. People stayed home with family and friends. It was ideal. Since most of the population went to a church, it was a good time to share the gospel teach the congregation and have activities for fellowship and ministry. Non Church-goers are generally available during traditional Sunday services. How many people could we have an impact on, if we stayed home, cooked breakfast and invited our neighbors and friends over?
2) The Worship Experience.
There is a reason why many events are held in the evenings. There is a certain natural vulnerability in the evenings. Most of my deep conversations have been in the evenings. Worship on Sunday nights to me has always been much more intimate. To me all of the efforts put forth on a Sunday morning could be multiplied simply by moving to a Friday, Saturday, or Sunday night.
