There are always two spirits at work: the Holy Ghost and a satanic or false spirit. Witchcraft comes from a satanic spirit and opposes God's Spirit.
God expects His people to avoid unholy practices (i.e., divination, observing of times, witchcraft, wizardry, necromancing) that ensnare the world.
Seeking counsel or instruction from spirits or from the deceased is a wicked practice and demands God's righteous judgment.
Many unsaved people practice astrology (i.e., horoscopes) and other unscriptural use of the signs in the heavens. Believers should reject these practices.
In Deuteronomy 7:7-8, the Lord expressed His great love for the nation of Israel. In the midst of this declaration, the Lord provided reasons why He placed His love upon this particular nation. In Deuteronomy 1:27, the people began to murmur and their murmurings bred lies. They stated that the Lord brought them out of Egypt to destroy them because of His great hatred for them. Their statements were completely false. This is true in most circumstances when people turn to murmuring. The problem gets exaggerated and the truth corrupted. Fabricating lies helps the one murmuring to feel better about voicing the complaint. Interestingly, the truth is usually not worth murmuring about.
