That means we must give our lives for other believers. ¹⁷ Now, suppose a person has enough to live on and notices another believer in need. How can God’s love be in that person if he doesn’t bother to help the other believer? ¹⁸ Dear children, we must show love through actions that are sincere, not through empty words.
