What power does Satan use to cause boils to break out on Jobs body or for his children to die? White Magic as all forms of magic has it's roots in Satan.The black arts which people use instead of having faith in God and his power.The Truth and Spirit is what we as believers must abide in. Trusting God to provide all our needs.
Isaiah 47:10-15 (King James Version) 10.For thou hast trusted in thy wickedness: thou hast said, None seeth me. Thy wisdom and thy knowledge, it hath perverted thee; and thou hast said in thine heart, I am, and none else beside me. 11.Therefore shall evil come upon thee; thou shalt not know from whence it riseth: and mischief shall fall upon thee; thou shalt not be able to put it off: and desolation shall come upon thee suddenly, which thou shalt not know.
12.Stand now with thine enchantments, and with the multitude of thy sorceries, wherein thou hast laboured from thy youth; if so be thou shalt be able to profit, if so be thou mayest prevail. 13.Thou art wearied in the multitude of thy counsels. Let now the astrologers, the stargazers, the monthly prognosticators, stand up, and save thee from these things that shall come upon thee. 14.Behold, they shall be as stubble; the fire shall burn them; they shall not deliver themselves from the power of the flame: there shall not be a coal to warm at, nor fire to sit before it. 15.Thus shall they be unto thee with whom thou hast laboured, even thy merchants, from thy youth: they shall wander every one to his quarter; none shall save thee.
