A Steadfast Mind (2)

And there are three parts of this steadfastness of the mind:

(1) full purpose of cleaving to God in all things;

(2) a daily renovation and quickening of the heart unto a discharge of this purpose;

(3) resolutions against all dalliances or parleys about negligence in that discharge…

A Steadfast Mind

The steadfastness of our minds abiding in their duty is the cause of all our unmovableness and fruitfulness in obedience; and so Peter tells us that those who are by any means led away or enticed “fall from their own steadfastness” (2 Pet. 3:17). And the great blame that is laid upon backsliders is that they are not steadfast: “Their heart was not steadfast” (Ps. 78:37). For if the soul be safe, unless the mind be drawn off from its duty, the soundness and steadfastness of the mind is its great preservative.

The Mind and Sin’s Deceitfulness

In ch. 8 of his The Power and Efficacy of Indwelling Sin, John Owen elaborates on Hebrews 3:13 (“Take heed that you be not hardened by the deceitfulness of sin”) and discusses the role of the mind in the deceitfulness of sin:

Deceit properly affects the mind; it is the mind that is deceived… But where the mind is tainted, the prevalency must be great; for the mind or understanding is the leading faculty of the soul, and what that fixes on the will and affections rush after, being capable of no consideration but what that presents to them. Hence it is, that though the entanglements of the affections unto sin be oftentimes most troublesome, yet the deceit of the mind is always most dangerous, and that because of the place that it possesses in the soul as unto all its operations.
