Consider what occasions, what advantages thy distemper hath taken to exert and put forth itself, and watch against them all.
This is one part of that duty which our blessed Saviour recommends to his disciples under the name of watching: Mark xiii. 37, “I say unto you all, Watch;” which, in Luke xxi. 34, is, “Take heed lest your hearts be overcharged.” Watch against all eruptions of thy corruptions. I mean that duty which David professed himself to be exercised unto. “I have,” saith he, “kept myself from mine iniquity.” He watched all the ways and workings of his iniquity, to prevent them, to rise up against them. This is that which we are called unto under the name of “considering our ways.”
Consider what ways, what companies, what opportunities, what studies, what businesses, what conditions, have at any time given, or do usually give, advantages to thy distempers, and set thyself heedfully against them all.
Men will do this with respect unto their bodily infirmities and distempers. The seasons, the diet, the air that have proved offensive shall be avoided.
Are the things of the soul of less importance? Know that he that dares to dally with occasions of sin will dare to sin. He that will venture upon temptation unto wickedness will venture upon wickedness.
Hazael thought he should not be so wicked as the prophet told him he would be. To convince him, the prophet tells him no more but, “Thou shalt be king of Syria.”
