Okay kiddo, let me explain to you what "Man of Sorrows" means. So, you know how sometimes people feel really sad or upset? Well, there was a man named Jesus who lived a long time ago and he felt a lot of sadness and pain too. He was called the "Man of Sorrows" because he carried a lot of people's sadness and pain on his shoulders.
See, Jesus was a very special person who came to earth to help people and teach them about how to be kind and loving to one another. But some people didn't like him and they hurt him very badly. They made him carry a really heavy cross and nailed him to it until he died.
You might be wondering why people call him the "Man of Sorrows" if he was such a nice person. Well, it's because he took on the sadness and pain of all the people who were hurting and suffering at the time. Even though he was hurting too, he tried his best to comfort and help them. He showed them that he understood their pain and loved them no matter what.
So that's what "Man of Sorrows" means - it's a way of remembering the love and compassion that Jesus showed to everyone, even in the midst of his own suffering. And it reminds us that even when we feel sad and alone, we are never really alone because Jesus is there with us, sharing our pain and carrying it with us.
