If this is real, and not just messing with us, and you are actually seeing demons, you are facing serious spiritual attacks, and the cause therein doesn’t matter as much now, as it does for you to gain skills to fight back. Saturate yourself with learning about spiritual warfare first.
I’ll share some tidbits from my own experiences that have helped. One of them was something I found on my own, and it’s actually amusing to a point, with how effective it is. When you face these creatures, pray for them to see the light of Christ, and to let his Light permeate their beings…do so earnestly and you will see a remarkable, alarmed, fearful look on their faces while they suddenly retreat. Know in this war, you must stand strong and show no weakness, this means every single time you turned back, you showed them their tactics are being effective, the very act of turning back reinforces their resolve, and of course they will continue to use the same techniques, because they are effectively manipulating you to take action other then the ones you want to take.
Know that you fight from victory soldier, Christs victory, and this battle we face is only the aftermath of the war that they have lost. They are trying to go down kicking and screaming, because they know utter anialation awaits them, there are no prisoners in this war, nor are there any that switch sides. Fear NO evil, regardless of what you experience, fear it not because God is by your side, and with him nothing can stand against you. They use fear in a big way, that is where they draw their power from in order to get at you, it’s a lie for them to tell you to fear them, for you are much, much stronger then you think you are, but still, having Christ as the ultimate power, that the angels and saints are also right with you as well, their army is vastly inferior to ours. Think about this in terms of raw numbers, only 1/3 of the angels alone fell, this makes Gods army 2/3rds larger, and of course, they only have a finite being as their head, we have the infinite Lord All Mighty.
Their agenda is to keep you in bondage, and in bondage is where you are currently at, they hate losing victims. At the same time, those that have the greater benefit from experiencing our faith in full, are going to face the most opposition in the process.
Go back to RCIA, go back to Mass, let nothing stop you, this will show you what I mean in real time, it will also help to empower your thought process, knowing that you do have the ability to fight back because ultimately, it’s your free will, not theirs, not even Gods himself, it’s yours and yours alone, so choose not to back down and choose to seek the face of the Lord in all that you do and all that you are.
Here is a good starter book I recommend in this area: Chip Ingram, The Invisible War, it’s easy to read and understand, just needs a few odds and ends de-protestanized, but not something one with little discernment can’t figure out. You will learn that every single person on this planet fights this war, some are more aware of it then others, some also seem to be more on the front line then others.
