I am viewing the spiritual realm where the angels and demons, the things that physically we can't see, fight and exist. I want to know if there is proof that the Word of God, aka Sword of the Spirit, could or couldn't be more than just a sword.
Well, what do the Angels and Demons fight with?
Hell, Why exactly do you want to know? Why are you even asking this?
So you wouldn't believe me if I told you I could see that. I can agree that it is beyond our understanding, but that does not rule out that we can't see it. If that is the case, explain why Mary Kay Baxter, several friends I know, and I can see it.
No, and there is absolutely no way YOU can prove it, nor can Mary Baxter or your friends. If you could, then the concept of faith would be irrelevant, and Christianity itself would be pointless. There is no way you or anyone else can prove that you're really seeing into the spiritual realm.
Also, in her books, Mary Kay Baxter is speaking metaphorically when she refers to spiritual weaponry and war. It's time you realized that this warfare is not how you envision it.
We were put into existence to do God's will. The reason for us being where we are now is because of the sin Adam and Eve commited.
My point stands. You cannot be in the spiritual realm because of sin.
