Jer 10:5. Their idols are like scarecrows in a cucumber field, and they cannot speak; they have to be carried, for they cannot walk. Do not be afraid of them, for they cannot do evil, neither is it in them to do good."
It seems to me that the Lord is telling us that these things are somewhat neutral in themselves, niether good nor bad.
That would leave the onus on us then to not use them for evil. For those who do use them as a Christmas decoration, in honor of the Christ child, there is no evil intent.
Thanks for sharing that passage Bro.tan.
Yup that's exactly right. The vain "ways of the heathen" in this passage is their belief that things created by God or made by men have any power to do either good or evil (which is actually what brotan seems to be advocating we believe?). For example: cutting down a tree, decorating it into a cross, fastening in your church? Fine. Believing that cross you made has some sort of supernatural power? You'd believe that in vain.
