Prevention is always better than having to seek a cure. The best prevention in regard to safety of the spirit, of the mind, and of the soul is to be sealed with the indwelling Holy Spirit Of God.
If you are not sealed, and have tried repeatedly to become sealed, it probably is because the devil has assigned demons to restrain you, or to block you from becoming sealed.
Command every demon in, on, or around you to state its name and be beheaded. Command every demon restraining you, and every demon blocking your path to do the same. Don’t stop beheading them until you are fully sealed and raptured into God’s millennial or eternal kingdom.
The Lord God Almighty El Shaddai
