"the devils also believe and tremble."

Paul says "Now faith is the substance of things hoped for, the evidence of things not seen."

-This unlocks a powerful intangibility in the game of life, that's stymies blatant, vulgar materialism.  Behind our eyes, in our thinkgood, none of our lawn tractors or ATV's or big screen televisions can penetrate into the inner core, and like Charles Foster Kane, we would be sitting morose in a material wonderland like his Xanadu, but ultimately, despite the toys surrounding him, unhappy.

James says, "Yea, a man say, Thou hast faith, and I have works: shew my thy faith without thy works, and I will shew thee my faith by my works."

The casual reader would place a tension between between the faith dominated doctrine of Paul versus faith and works doctrine of James, and yet that reading is too superficial.  What we can say is that Paul emphasizes faith, but in the daily course, one's faith becomes evident to those around him.

"Thou believest that there is one God: thou doest well: the devils also believe, and tremble."

-Worship and gratitude are the paths of personal expression of faith, that and that alone, fervent, earnest prayer.  Because we have the doctrine of the omniscience of God, we are assured he knows all of us to our very core, that he has access to our innermost thoughts and dreams.  And then Jesus talked of thought-sin, that even a corrupt thought, as of a dissipation, condemns one, because plainly, even that kind of very subtle, internal sin, is quite apparent to God.
