Belief in Jesus means that people believe that Jesus was a very special person and that he was sent by God to teach us important things about how to live our lives. Some people believe that he was the son of God and that he can help us in our lives if we pray to him and try to follow his teachings. This belief is very important to some people and it gives them hope and strength when they face difficult times. Just like how we believe in our parents, teachers or friends, some people believe in Jesus to help them become better and stronger individuals in their lives.
