What does Ephesians 4:2 mean?

Living in a manner worthy of Christ's calling (Ephesians 4:1) includes four traits described in this verse. First, the Ephesians—and all Christians—are to live in humility. Christ called others to live with the humility of a child (Matthew 18:4) and taught, "Whoever exalts himself will be humbled, and whoever humbles himself will be exalted" (Matthew 23:12). Jesus was born in a humble manger, grew up in humble surroundings, lived a humble life, yet had a tremendous impact. Christ's followers are to likewise operate in humility.

Second, believers are to live with gentleness. Being gentle is part of the fruit of the Spirit (Galatians 5:23) and important in the life of every believer. This trait not only helps to avoid unnecessary conflict, it demonstrates the love we are meant to display at all times (John 13:34–35).

Third, believers are to exhibit patience. Patience is another part of the fruit of the Spirit (Galatians 5:22) and also a necessity if we are to show love to others. Elsewhere, Paul reminds believers that "love is patient" (1 Corinthians 13:4).

Fourth, believers are to live with love toward one another. Paul has mentioned this in Ephesians and other letters, especially in 1 Corinthians 13 where the "greatest of [God's gifts] is love." Particularly as it is used in the New Testament, "love" is not merely a feeling or an emotion. It means taking actions which benefit others. A feeling which doesn't result in action is not biblical "love."
