The state of inward recollection tends to diminish greatly the occasions of temptation. It is very obvious, that he, who knows nothing but his present duty in itself and in its relations, which is all that it is necessary for him to know, cannot be so much exposed in this respect, as other persons. Unspeakable dangers must, of necessity, beset the mind, which is full of worldly activity, and which is continually discursive: running upon errands where it is not called; curiously and unnecessarily speculative; prying oftentimes with microscopic minuteness, into the concerns of others, not only without reason but against reason. What a flood of tempting thoughts must flow out upon these various occasions, and throng around the mind! What suggestions, which Satan knows well when and where to apply, to envy, distrust, anger, pride, worldly pleasure, ambition; none of which probably would. have approached the mind that remained recollected in God.
