If you are a Christian with children, I strongly urge you to buy this book.
There is an important portion of scripture that many people are not familiar with:
Avoid Wicked Customs
9 “When you come into the land which the Lord your God is giving you, you shall not learn to follow the abominations of those nations. 10 There shall not be found among you anyone who makes his son or his daughter pass through the fire, or one who practices witchcraft, or a soothsayer, or one who interprets omens, or a sorcerer, 11 or one who conjures spells, or a medium, or a spiritist, or one who calls up the dead. 12 For all who do these things are an abomination to the Lord, and because of these abominations the Lord your God drives them out from before you. 13 You shall be blameless before the Lord your God. 14 For these nations which you will dispossess listened to soothsayers and diviners; but as for you, the Lord your God has not appointed such for you.
Buy the book for yourself and then ask God yourself.
