Why is it that most people do not believe in supernatural beings? Maybe, because they can't see it..hmmm okay good point, then I ask you this...God is the super-est super supernatural being in existence, you can't see Him? So...why do you believe in Him? Oh because you have faith!
Supernatural is something that is beyond its natural surroundings, its more powerful! Its able to do so much more than its natural surroundings! And also something that's able overpower its natural surroundings.
Angels are supernatural...and also fallen angels... they are everywhere! all the time! Its awesome right?
The bad news is that not everyone can see them...only a select few, handpicked by God.
And then those selected few can't always see them either...only sometimes...I think its because God said that somethings will always remain a secret...This is maybe one of those things? who knows? All I know is that its this way for a reason, and that reason is to protect us!
God sent His angels to protect us...and the Holy Ghost to guide us....these are supernatural things! And they exist! And if you have chosen to be a follower of Jesus Christ...believe it or not, your also supernatural, you'll live forever!
When you're supernatural you are able overpower your natural surroundings...the sinful world. You are able to chose against it! You have the power to! ...but we don't always do that...
Because we are supernatural beings destined to live forever, and we don't believe it....
We don't have faith....
