I agree with your post as some it does speak to what I also said, from a different perspective.
I have a question or two though, what is the purpose of a revival in the West today, and why not include the East? Do I even agree with even this? Not at all, because strictly speaking, it is not the nations as a whole that need revival, believers cannot revive evil in their midst to Christ or mix with it, within nations. There is no such thing as a pure 100% Christian nation; even in OT of the 12 tribes of Israel, not all were believers. Never was and never will be for obvious reasons.
Now, a revival via the Spirit, to strengthen and re-weld loosened bonds within the ekklesia only, is my hope and prayer, indeed, where ever they are living on this planet. And especially today, to be strong, vigilant, as we eagerly await our Saviour, in glory and power.
I have not forgotten about this post, but I decided to create a new thread about this topic of Revival, as there are enough politics at the moment, my answer to these questions is the spark of revival has already been ignited in many of the Eastern Nations, and many of these are persecuted nations or third world countries.
A few months ago missionaries from CFaN were preaching the Gospel, the good news about Jesus Christ in an African country, I don't remember which country, but in just 3 weeks, 200 thousand people gave their lives to Jesus. In the Middle East we are also continuously hear people turn to Jesus, whether if it be through dreams, visions directly from Jesus, missionaries going to spread the gospel in these places, or people seeking for the real God, with Islamic extremism being revealed, as a result they no longer want to associate themselves with a false religion. Also I believe there continue to be many people converting to Jesus in many of the Asian persecuted nations.
It's in many of these Eastern nations where the Harvest is large, ripe and plentiful and the moment, this is where many are willing to hear the Gospel, these are the places where many are willing to hear the good news of Jesus, and see Jesus work miracles in their lives.
And yes you are right revival is needed all around. As Revival is not just the bringing in of the lost to Jesus, but it is also re-igniting the flame and fire in many Christian lives as well, even in a country that is 90% + Christian, there is a need to be revived, to make sure that they don't become the sleeping Church.
Some have even said that revival will take place in those persecuted nations first and spread out into the West..
The difference is readiness and openness. Of course persecution also plays a part, because these people are living in the position of books of Acts where persecution does come when they do preach the Gospel, and they got to trust God entirely, you know I have even heard some ex-muslim converts say that they no longer fear the threat of rape, because they have given their lives to Jesus, they have set aside their lives as a sacrifice to go do the work of God, and these are both men and women. This is the courage they have.
