151. Believing in the Lord is not merely acknowledging Him but also doing His commandments; for simply acknowledging Him is solely a matter of thought, arising from somewhat of the understanding; but doing His commandments is also a matter of acknowledgment from the will. Man's mind consists of understanding and will; and as the understanding deals with thinking and the will with doing, so when man's acknowledgment is merely from the thought of the understanding he comes to the Lord with only half of his mind; but when there is doing he comes with all of it; and this is to believe. But on the other hand, man is able to divide his heart, and to force the outermost of his nature to soar aloft, the flesh in him meanwhile turning downward; thus he flies like an eagle between heaven and hell. And yet, the man himself does not follow his [upward] look, but the delight of his flesh; and this he does because he is in hell; therefore to hell he flies; and when he has there sacrificed to his voluptuous pleasures and poured out libations to demons, he puts on a countenance of merriment, and his eyes sparkle with fire, and so he feigns himself an angel of light. Such satans do those become after death who acknowledge the Lord but do not keep His commandments.
