The concept of a clean heart is the concept of ____.

• A. Outward holiness
• B. Inward holiness
• C. Ceremonial purity
• D. Ethical perfection

Answer: (B)

A clean heart means inward holiness—the cleansing of the heart’s desires and motivations from sin, accomplished by the Holy Spirit, which results in a transformed inner life that loves and serves God. In biblical thought, the heart is the seat of the will and affections; when it is cleansed, the governing loves are oriented away from sin and toward God, producing true sanctification from the inside out.

This is not about outward appearances or external rules. Outward holiness focuses on how a person looks or behaves on the outside, while ceremonial purity refers to ritual cleanliness. The term clean heart points to the inner cleansing that makes genuine obedience possible, rather than merely meeting external standards. It’s also not simply ethical perfection as an external goal; rather, inward holiness is the basis from which righteous living flows.

In Church of God teaching, the clean heart is closely tied to the experience of entire sanctification—a definite inner cleansing by the Holy Spirit that enables holy living.
