Ginnyrose,
Thank you for sharing your heart. Life can certainly get complicated and the life of the Church is no exception. I can appreciate you approaching the subject with caution and concern.
I would like to answer your question about the examples of corporate repentance in the New Testament. The clearest examples would be found in Revelation 2 and 3. These seven churches are both praised and rebuked with warnings that are quite severe!
“But I have this against you, that you have left your first love. Therefore remember from where you have fallen, and repent and do the deeds you did at first; or else I am coming to you and will remove your lampstand out of its place - unless you repent.” (Revelation 2:4, 5)
It is this warning, “I will remove your lampstand” which forms the basis of the teaching that corporate repentance is still required and that the neglect of such has dire consequences.
Ask yourself, “Do any of the churches in the New Testament exist today? If not, why not? Have their lampstands been removed?”
To the Nicolatians of Pergamum, this solemn warning, “Therefore repent; or else I am coming to you quickly, and I will make war against them with the sword of My mouth.” (Revelation 2:17)
The Lord’s hatred of sin has not abated and He is still a warrior. (Exodus 15:3)
On a larger scale, the same truth can be applied to denominations. Consider how God used John and Charles Wesley but what is Methodism today? Consider Congregationalists like John Owen and Jonathan Edwards. How many modern Christians even know that this denomination still exists (and in a form radically different than it was a few hundred years ago)?
What church/denomination that was used mightily of God in the past is still a thriving center of spiritual zeal?
The principle applies to nations as well. What happened to the vast Roman Empire? How many nations that grew spiritually in seasons of revival have retained that same blessing and influence?
Lastly, consider America’s founding in comparison to her spiritual life today? Is corporate repentance required of this nation?
Isn’t that why we pray for revival?
Grace and peace,
Matthew
