Jesus' ministry refers to the period during which Jesus of Nazareth preached, taught, and performed miracles in the regions of Galilee and Judea. It is generally believed to have lasted about three years, beginning when he was around 30 years old. His teachings focused on love, forgiveness, and the coming of the Kingdom of God, often conveyed through parables. During his ministry, Jesus gathered a group of followers known as the disciples, who helped spread his message. He performed various miracles, such as healing the sick and feeding the hungry, which demonstrated his compassion and authority. His actions and teachings laid the foundation for what would later become Christianity.
