So wish them well. What on earth does that have to do with wishing them a good holiday which they don't believe in.
" I hope you have a nice time celebrating the birth of a man you reject". HUH?
on a and hope for them to gain blessings?
Good, go hope. And pray for them too while your at it. And tell them you are praying for them if you want.
But don't be surprised if they look at you funny when you tell them you are praying for them to a God they say doesn't exist. Makes perfect sense,,,,HUH?
Peace on Earth, good will to men, all that stuff?
Good stuff, has nothing to do with Merry Christmas though.
While your at it, don't set your goals so low. Peace is the absence of conflict. Why not wish the world harmony?
"What on earth does that have to do with wishing them a good holiday which they don't believe in."
Possibly because wishing them a good holiday that they know YOU believe in might help them feel like maybe someday listening to you tell them about that holiday? About why it is important to you? Might not work out that way, but it also might. Worth a try.
