Sorry you have having a hard time understanding. But Christians have no choice in their stand against witchcraft and wizardry. Here is a couple of Scriptures from the OT:
1 Samuel 15:23 For rebellion is as the sin of witchcraft, and stubbornness is as iniquity and idolatry. Because thou hast rejected the word of the LORD, he hath also rejected thee from being king. {witchcraft: Heb. divination}
2 Chronicles 33:6 And he caused his children to pass through the fire in the valley of the son of Hinnom: also he observed times, and used enchantments, and used witchcraft, and dealt with a familiar spirit, and with wizards: he wrought much evil in the sight of the LORD, to provoke him to anger.
Here is one more you may find interesting:
Exodus 22:18 Thou shalt not suffer a witch to live.
Now from the NT:
Ephesians 5: 19, 20: "Now the works of the flesh are manifest, which are these; Adultery, fornication, uncleanness, lasciviousness, Idolatry, witchcraft, hatred, variance, emulations, wrath, strife, seditions, heresies,...."
A couple more jewels from the OT:
Leviticus 20:27 A man also or woman that hath a familiar spirit, or that is a wizard, shall surely be put to death: they shall stone them with stones: their blood shall be upon them.
Check this out to get a feel for how God views this:
1 Samuel 28:8 And Saul disguised himself, and put on other raiment, and he went, and two men with him, and they came to the woman by night: and he said, I pray thee, divine unto me by the familiar spirit, and bring me him up, whom I shall name unto thee.
1 Chronicles 10:13 So Saul died for his transgression which he committed against the LORD, even against the word of the LORD, which he kept not, and also for asking counsel of one that had a familiar spirit, to enquire of it; {committed: Heb. transgressed}
Hope this helps.
