The practice of witchcraft is forbidden by God. It's in the Bible, Deuteronomy 18:9-13, NIV. "When you enter the land the Lord your God is giving you, do not learn to imitate the detestable ways of the nations there. Let no one be found among you who sacrifices his son or daughter in the fire, who practices divination or sorcery, interprets omens, engages in witchcraft, or casts spells, or who is a medium or spiritist or who consults the dead. Anyone who does these things is detestable to the Lord, and because of these detestable practices the Lord your God will drive out those nations before you. You must be blameless before the Lord your God."
Those who practice witchcraft will not inherit the kingdom of God. It's in the Bible, Galatians 5:19-21, NIV. "The acts of the sinful nature are obvious: sexual immorality, impurity and debauchery; idolatry and witchcraft; …drunkenness, orgies, and the like. I warn you, as I did before, that those who live like this will not inherit the kingdom of God."
The future is known only by God, not witches. It's in the Bible, Isaiah 8:19, TLB. "So why are you trying to find out the future by consulting witches and mediums. Don't listen to their whisperings and mutterings. Can the living find out the future from the dead? Why not ask your God?"
