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.
The prevailing philosophy today seems to be that each person should be allowed to do what is right in his own eyes. With this philosophy, anything goes! Unfortunately, even Christians have bought into this wicked mindset as they raise their children and allow them to decide what to believe to be true. This contradicts the very foundation of biblical faith that teaches believers to pass on the truths that they have received. The Lord called Moses to the mount to receive commandments with the end purpose that he would teach the people what he had received. This theme was quite common in the history of the nation of Israel (Deuteronomy 4:9-10). God gave His truth to His people with instructions to give those truths to others. The New Testament follows this same pattern. “And the things that thou hast heard of me among many witnesses, the same commit thou to faithful men, who shall be able to teach others also” (2 Timothy 2:2).
