We are slow to know ourselves, and sometimes do not wish to; purposes form in the background of our minds, of which we are hardly conscious; latent motives actuate us; perhaps our own words or deeds, in which they suddenly issue, startle us; we are amazed that we should have said or done such a thing. But it is no surprise to Him. “Thou understandest my thought afar off.” Such knowledge of man by God is quite different from omniscience. Omniscience is a divine attribute, but what is here experienced is a divine action—it is God through His searching knowledge of us entering with power into our lives. It is God besetting us behind and before, and laying His hand upon us.
James Denney
I have learned in my short days upon the Earth that not every thought in my mind is my own. Most originate from my own will, desire and reason. But a large number are fed into the stream of background chatter of my mind by spiritual entities of pure evil. And a small number, the quiet and small sounding ones, come from our Lord Himself. What my job has become is to vett each thought for its origin and reject the ones fed into my mind by the enemies of my soul.
