Jesus had many friends, including John the Baptist, Lazarus, Mary and Martha, and the 12 disciples.
John the Baptist
John lived in the wilderness near the Jordan River. Many people came to hear John preach about repentance and the coming of Christ. John baptized people in the river for the forgiveness of sins.
Although Jesus never sinned, he was baptized by John. When Jesus came up from the water, the Holy Spirit descended, and God spoke from heaven, saying "This is my beloved son."
John the Baptist rebuked Herod Antipas for his evil deeds, and for marrying his brother's wife. Herod imprisoned John for this, and later had him executed.
Lazarus, Mary, and Martha
Lazarus and his sisters, Mary and Martha, lived in Bethany outside Jerusalem. On multiple occasions they served Jesus and his disciples.
Near the end of Jesus' ministry, Lazarus died and was buried. Four days after Lazarus died, Jesus visited the sisters. He was deeply grieved, and raised Lazarus from the dead.
The disciples were men Jesus selected as companions. They had different backgrounds. Jesus chose fishermen, a tax collector, a twin, and others. They travelled with Jesus as he preached. After Jesus died, they taught others about him.
These men were also called apostles. Their names were Peter, Andrew, James the son of Zebedee, John, Philip, Bartholomew, Matthew, Thomas, James the son of Alpheus, Thaddeus, Simon, and Judas Iscariot.
