I have no problem with Christmas trees either. I just keep it all in perspective. I did a short study on Diana, Artemis, Ashtoreth and other strange things. Eye opening. It is already 10:15 AM on Dec 24 here, but still Tuesday there. We will celebrate Christmas tomorrow, even though I seriously question the date of Jesus' birth. I just keep it in perspective. Uphold good, sound Biblical doctrine. Maligayang Pasko.
There are folks for whom “Christmas” really does seem to be about the trappings. I knew a guy like that, a frank unbeliever, who had a Christmas tree so big he had to cut it off to get it into his mansion’s two story atrium... he never measured the silly space.
At any rate when the devil comes calling, Jesus will send him on the run. Might be quick, might take some time, but He will.
And in a sense, every day should be a Christmas, every day should be an Easter. Neither of these were given by the Lord as ordinances and the matter falls within the realm of Christian freedom. They are voluntary symbols. But keeping the witness up “in season” (as well as out) has a value.
