The Greek word psýchō, represented by G5594, is a primary verb that figuratively means to chill or wax cold. The base definition involves gentle breathing, which by implication suggests a reduction in temperature. It appears just 1 time in 1 unique verse, making its single usage highly significant.
The sole biblical appearance of G5594 is in a prophetic context. In Matthew 24:12, it is used to describe the consequence of rising lawlessness, stating that because iniquity shall abound, the love of many shall wax cold. This positions the word as a key indicator of spiritual decline, directly linking the chilling of affection to the increase of sin.
Several related words from its only context help clarify its meaning:
- G458 anomía (iniquity): This word, defined as "illegality, i.e. violation of law," is the direct cause of the love that waxes cold. It is described as the essence of sin, as "sin is the transgression of the law" 1 John 3:4.
- G4129 plēthýnō (abound): This term means "to increase" or "multiply." In Matthew 24:12, it describes the proliferation of iniquity. It is also used in a positive sense, such as when the number of disciples "multiplied" in Jerusalem Acts 6:7.
- G26 agápē (love): This is what is affected by the chilling action of G5594. It refers to "affection or benevolence" and is presented as a foundational Christian virtue, the greatest of which is "charity" 1 Corinthians 13:13.
The theological weight of G5594 is concentrated in its single, powerful use.
- Spiritual Cause and Effect: The word establishes a clear principle: an environment of increasing iniquity G458 will have a direct, chilling effect on the love G26 of believers.
- A Prophetic Sign: The "waxing cold" of love is presented as a specific sign of the end times. It serves as a warning against the spiritual indifference that can result from exposure to widespread lawlessness.
- The Nature of Love: Its usage implies that love (agápē) is not a static emotion but a vibrant, "warm" commitment that can diminish and grow cold if not actively protected from the corrupting influence of iniquity.
In summary, G5594 provides a critical, though singular, piece of biblical vocabulary. It uniquely conveys the idea of a spiritual chilling. Its use in Matthew 24:12 is a stark reminder of the fragile nature of love in a fallen world, illustrating how unchecked iniquity leads to a cooling of the very affection that should define the believer. The word serves as a potent warning about the relationship between sin and spiritual vitality.
