This passage from Ephesians encourages Christians to imitate God through living in love and avoiding sinful behaviors like sexual immorality, greed, and crude speech. It warns that those who engage in such behaviors will not inherit God's kingdom. Christians are instead called to live as children of light by behaving in ways that are good, righteous, and truthful. They should make the most of their time and understand God's will, rather than participating in fruitless works of darkness.
