There is a lot said within the bible on what God cares for doing. Jesus died for our sins yes as he is the son of God, but he is also God HIMSELF. The Father, Son and the Holy Spirit all are the same and all are one. At the time of the New Testament there were plenty of Black Magick users than White Magick users, so therefore White Magick and Positive magick was given a bad rep. This thought was brought to mind when the people making the bible, putting together what should be learned and what shouldn't be learned back then. I am a Christian Wiccan, meaning I do magick AND I believe fully in Jesus. Magick is done all the time for full-on Christians as well, during prayer, during choirs with their song magick enchanting the listeners so epically. And for the experienced Christian, he may learn how to speak to God himself, through listening literally to their hearts, as I have done, and I have been told that by God, White Magick, is acceptable. Even Jesus understands that "With harm to none, do as thy will." but within the Christian rules as well, do as thy will.
Blessed Be and Amen.
