Can you be a witch and still serve the christan God?

No, you cannot be both because Christianity is a personal relationship with Jesus Christ

Both these things are imaginary, so you should be fine.

the bible is very clear , we are instructed to reject all forms of witchcraft and divination. You must eventually choose one of the other, serve your desires or serve the Will Of God.Jesus himself said that you “cannot serve two masters”

From a Wiccan point of view: Yes. Wicca does not require you to cast aside any previous religious beliefs that you have. All deities are viewed as facets of the same gem.
From a Christian point of view: No chance in hell.

No witch craft is wrong.That involve with spirtism it says in the Bible.It say about people believing in tarot card,astrology and witch craft.People used to study them.They all got together and burned the books.You can not serve God and continue to do defiled or unclean things.

Not a chance, the Bible says. Thou shall not suffer a witch to live.

Witchcraft is a manifested work of the flesh (Galatians 5:20-21).
The acts of the sinful nature are obvious: sexual immorality, impurity and debauchery; idolatry and witchcraft; hatred, discord, jealousy, fits of rage, selfish ambition, dissensions, factions and envy; 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.
(Galatians 5: 22-25)
But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness and self-control. Against such things there is no law. Those who belong to Christ Jesus have crucified the sinful nature with its passions and desires. Since we live by the Spirit, let us keep in step with the Spirit.

Yes. The verse “thou shalt not suffer a witch to live” actually is supposed to say poisoner, not witch.

It depends on whose perspective.
There are Christian Witches. They don’t believe they are going against the Christian God.
There are Christians who think that all Witchcraft goes against their God, period.
There are many Witches who are not Christian… many religions accept the practice of Witchcraft, so these Witches will just follow their own faith and Gods.
That doesn’t mean they are against the Christian God… they just don’t believe in the Christian concept of God. Like you might not believe in the tooth fairy, but that doesn’t mean you are against the tooth fairy. The tooth fairy is irrelevant. So are Gods (or Goddesses) you don’t believe in.

You can, in that Witchcraft is not a religion so a Witch may be of any religion or no religion at all and still practice. (Wicca is a religion, therefore one cannot be of two religions and serve them both faithfully).
HOWEVER…The Christian God forbids the work of Witchcraft, divination, mediumship, etc. (see Deut. 10) so I don’t see how any faithful Christian would **want** to practice Witchcraft and still be sure they are pleasing God.
Here are further thoughts on Christians wanting to explore Witchcraft/Wicca

Perhaps you should look into Christian mysticism instead of witchcraft.
