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
The key in these verses is to understand that Paul speaks of a specific knowledge—the knowledge of God's will, God's knowledge. It is not knowledge about God but God's knowledge that we receive through study, teaching, and practice.

The Covenants, Grace, and Law (Part Twenty)
Our joy through trials is a result of suffering for Christ's sake. Of the persecution we must endure, Jesus says, "Rejoice in that day and leap for joy!" (Luke 6:23). Through the Holy Spirit, God gives us His gift of joy as part of the process of spiritual completion.
