When we are consciously and deliberately doing God's will, we are happy. When we are not, we are not. In the nature of things it HAS to be that way. And in the reality of things, it IS that way. Analyze it through, and you will find it so. Any other "pleasure" has to be, and is, self-deception: an ignorant or deliberate self-blinding, a shutting out of reality and consequence, a desperate, warped, juvenile submersion in the present to drown the pain of natural life's meaninglessness and emptiness, to briefly dim the final, inescapable, staring face of eternal death.
