Why did God Bless The United Kingdom?

They sold their soul to Satan and the Jews in exchange for brief temporal power. I say this as an ex Anglican englishman

England has apostesized from all faith and is a failed state being picked over by Muslim rape gangs now. Maybe God plays the long game?

This isn't the end of the story, but He always plays the long game. See how long it took for the incarnation so He could get the Truth out there at the perfect time for it to spread.

Your question is ridiculous. Why did God allow mahomet to claim an enormous empire with the lies of the Quran?
Did he bless him and his demonic doctrine?
And the UK is going down the toilet soon, the muslims are going to be majority in no time.

It was judgement on the Christians who had begun worshipping idols

Literally retarded. Only protestants would think like that.
Why do your countries go down the toilet, while Orthodox ones are much more faithful?

Notice how Britain fell immediately following Ireland's leaving. Ireland was holding up the Union.

This.
OP, you may as well ask why Muslim nations exist in a large numbers. Besides, most Protestant/Catholic countries are either atheistic or agnostic. If the people in Brazil or Mexico for example followed and believed in the Bible, then would you still see the crime rates they have there?

Dead ceremony isn't faith

In just the last few years Ireland has been undergoing a mass apostasy at a breathtaking rate. It's no longer a bastion of Catholicism.
