“God does not want His church to take pagan days, and those pagan and popish rites and paraphernalia that go with them, and adapt them to Christian use. He simply commands us to abolish them altogether from the face of the earth forever. You may not be offended by the Yule log, the Christmas tree, the mistletoe, the holly berries and the selection of a pagan day to celebrate Christ’s birth, but God is offended. God commands us to get rid of the monuments and paraphernalia of paganism.
If your wife was promiscuous before you married her would you be offended if she had pictures of her old boyfriends on her dresser? Would it bother you if she celebrated the various anniversaries relating to her past relationships? Would you be offended if she kept and cherished the various rings, jewelry and mementos given to her by her old boyfriends? Of course you would be offended! The Lord God is infinitely more zealous of His honor than you are; He is a jealous God. Could Israel take festival days to Baal, Ashteroth, Dagon and Molech and alter them to make them pleasing to God? Of course not! The Bible makes very clear which kings of Judah pleased God the most. God is pleased when idols, their temples, their religious dress, earrings, sacred houses, sacred trees, poles, ornaments, rites, names and days are utterly cut off from the earth, never again to be restored. God wants His bride to eliminate forever the monuments, the days, the paraphernalia and the mementos of idolatry. “Do not learn the way of the Gentiles; do not be dismayed at the signs of heaven, for the Gentiles are dismayed at them. For the customs of the people are futile…” (Jer. 10:2-3). “You shall not worship the Lord your God in that way; for every abomination to the Lord, which he hates they have done to their gods…” (Deut. 12:31).””
