John Nelson Darby emphasizes the profound unselfishness of Christ, noting that every action of Jesus was directed towards serving others rather than Himself. He contrasts this with the world's principle of self-seeking, where individuals pursue their own interests and pleasures, often at the expense of true moral motives. Darby argues that even those who appear moral or philanthropic are often driven by selfish motives, lacking the genuine love and compassion that characterized Christ's life. He challenges Christians to embody the selfless nature of Christ, who tirelessly served others despite His own needs and hardships. Ultimately, Darby warns that if one's life does not reflect the unselfishness of Christ, they are not truly following Him.
