Little children, let us not love in word or talk but in deed and in truth.
1 John 3:18

The apostolic directive is a reminder that talk is cheap, but actions are enduring. But there is much more. For the paragraph begins with the Lord Jesus. Considering Him and His work, the apostle speaks about unconditional love. The definition of true love is to lay down one’s life for someone else. In the case of Jesus it is clear that we were loved while we were still enemies. That selfsacrificing love is the cause and goal for believers to do likewise.
