Agreed<quoted text>I appreciate your response. And you are, for the most part, right. BUT...
Thou believest that there is one God; thou doest well: the devils also believe, and tremble.
What separates us from devils?
The devils believe in "God," having been in His very presence. Faith is unnecessary for devils, for they dwell in the spirit-realm with "God." Their belief isn't based on testimonies and what-not. They know "God" exists because they've seen "God," face to face. But, they're not obedient. So, again, what separates us from devils?
The answer to the question as to who is an unbeliever, the answer is the first two.
To believe in "God" and His only-begotten Son isn't enough. As it's written, even the devils believe in "God." But, like I said and as we all know, devils aren't obedient. Therefore, we must do whatever is necessary to separate us from devils. In that, we must be obedient. Many of the most notorious criminals in history believed in "God," but in that, their belief only goes as far as believing "God" exists. We're not to believe "God" exists. We're to know "God" exists. But, we're to believe in Him. We're to believe that all that's prophesied will come to pass. We're to believe that He will fulfill every promise. And along with these, we're to believe that He rewards those that seek Him.
Little children, let no man deceive you: he that doeth righteousness is righteous, even as he is righteous.
According to Christianity, even Satan believes in Jesus.
Thus belief isn't enough.
