From A Faithful Narrative of the Surprising Work of God by Jonathan Edwards.

And then it was, in the latter part of December, that the spirit of God began extraordinarily to set in, and wonderfully to work amongst us; and there were, very suddenly, one after another, five or six persons, who were to all appearances savingly converted, and some of them wrought upon in a very remarkable manner.

Particularly, I was surprised with the relation of a young woman, who had been one of the greatest company-keepers in the whole town. When she came to me, I had never heard that she was become in any wise serious, but by the conversation I then had with her, it appeared to me, that what she gave an account of, was a glorious work of God’s infinite power and sovereign grace; and that God had given her a new heart, truly broken and sanctified. I could not then doubt of it, and have seen much in my acquaintance with her since to confirm it.

What a wonderful Christmas celebration, even if the Puritans didn’t celebrate Christmas!
