@neologist,
One has to find out who their demons are. And find their guardian angel. And find out where every thought is coming from inside themselves.
2 Cor 10:3-5
3 For though we walk in the flesh, we do not war according to the flesh.
4 For the weapons of our warfare are not carnal but mighty in God for pulling down strongholds,
5 casting down arguments and every high thing that exalts itself against the knowledge of God, bringing every thought into captivity to the obedience of Christ,
(NKJ)
