ELI5: Explain Like I'm 5

Knowledge of Christ

Okay kiddo, so the "knowledge of Christ" means knowing about Jesus and what he taught. Just like how you know about your family and friends, people who follow Jesus want to know all about him and his teachings. They learn about him by reading a special book called the Bible and listening to teachers talk about him. They believe that knowing about Jesus can help them make good choices and be better people. Does that make sense?
