If you have fed the enemy for years and years and even lifetimes, then your enemy is extremely powerful, and it is not going to leave without a fight. Remember it is a life you have created, albeit a negative life with improper energies, but it is still a life, and life seeks to live no matter what it takes. Life has to evolve. But the good news is evil can never exist without the veil of illusion. It does not exist within our divine world that we are all inheritors of.
Evil has to feed off the lowest form of energy to exist.
However, divine purity exists beyond the illusion into the spirit world of righteousness. Thereby as the Bible affirms, place your riches in heaven where dust and moth can not corrupt. When you begin to recreate your higher energies of life and love then you will create a life that is unparalleled. Nothing can come against it. As you create this energy of life and love, it will seek to feed off you, as did the negative energy.
