Harden not your hearts, as in the provocation, in the day of temptation in the wilderness: Hebrews 3:8
There is a natural hardness of the heart; the heart of man is like a stone, destitute of spiritual life, motion, and activity; it is senseless, stupid, impenitent, stubborn, and inflexible, on which no impressions can be made, but by powerful grace: and there is an acquired, habitual, and voluntary hardness of heart, to which men arrive by various steps; as entertaining pleasing thoughts of sin; an actual commission of it, with frequency, till it becomes customary, and so habitual; an extenuation or justification of it, and so they become hardened against all reproofs and sermons, and to all afflictions and judgments; are insensible and past feeling, and openly declare for sin, and glory in it: and there is a hardness which God’s people are liable to, and should guard against; and which is brought on by a neglect of private and public worship, and by keeping bad company, and through the ill examples of others, and by giving way to lesser sins; for all sin is of an hardening nature:
