Commentaries:
Paul tells the saints in Colosse that he prays they will possess the trait that is the opposite of wrath or revenge. He speaks of having an even temper, an attitude that in spite of injury or insult does not retaliate. We can develop longsuffering only as a fruit of the Spirit, not as an independent character trait. It grows from the common root of love and bears fruit only along with other spiritual fruit.

Longsuffering
In the New Testament, the most common Greek word for self-control (temperance, KJV) is enkrateia. Its root meaning is "power over oneself" or "self-mastery." Self-control, in its widest sense, is mastery over our passions. It is the virtue that holds our appetites in check, controlling our rational will or regulating our conduct without being duly swayed by sensuous desires. Moderation is a key element in self-control.
