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.
People in the world are generally quite self-centered. Even saved people are often lovers of their own selves instead of preferring one another.
How would making your motive match the Lord's motive change how you approach the Christian life (from witnessing to praying to Bible reading and so on)?
