You've got it so wrong with your lack of understanding.. on the contrary, we are joyous/happy people who celebrate life (that Jehovah God gives us) in sharing the Good news of the Bible with everyone (about the coming of God's Kingdom to be established soon here on a paradise earth).
I do lack understanding.
As for the "good news" that you spread: the news that the majority of humankind will soon be rendered to cinders by God....
Some good news.
No wonder I lack understanding
Anyway I'm off to celebrate Christmas with a dozen people who will arrive at our house soon, half of whom have no local friends or family. I think this is a better way of spreading good news than to a promise that they will roast if they don't embrace your prescription.
May you have a merry and blessed Christmas that is free of the fear of your warlike God hell bent on revenge.
