I have posted about growth in my church in another thread. I have also been aware of increasing numbers in other churches, but here's an article that confirms that something is happening more generally in UK churches.

If it is revival, it's starting from a very low base. As the article states, numbers in UK churches have been declining since 1858 (!) with just a small blip after WW2.
Please pray that something really great will come from this.

The Quiet Revival: Growth in the UK Church - FIEC
Signs of new evangelical life in the UK from "The Quiet Revival" report should encourage us to have confidence in the gospel and to persevere in gospel ministry.

Please pray that something really great will come from this.
