Who was John in the Bible

John was one of the 12 disciples of Jesus, he was called along with his brother James while they were fishing. He is often referred to as the apostle Jesus loved AMD was given the special responsibility of taking care of Mary after the death of Jesus.

When Jesus saw his mother there, and the disciple whom he loved standing nearby, he said to his mother, “Dear woman, here is your son.” JOHN 19:26

The disciple whom Jesus loved.” What title could anyone possibly want more than this? This title was the distinct privilege of the apostle John, the writer of the Gospel and letters that bear his name (John 13:23; 19:26; 21:7, 20).
We first read about John when he is chosen along with his brother James to leave his profession as a fisherman and become one of Jesus’ disciples. John and his brother must have been somewhat of a rowdy pair, because Jesus nicknamed them “Sons of Thunder” (Mark 3:17).
Nevertheless, John held some special place in Jesus’ heart, because he was included in Jesus’ “inner circle” of followers (Mark 5:37; 9:2; 13:3; 14:33) and was specifically given the responsibility to take care of Jesus’ mother as Jesus neared death (John 19:26–27).
Soon after Jesus’ resurrection, John and Peter healed a crippled man and were thrown into prison for preaching in the name of Jesus (Acts 3–4). Later John and Peter were sent to Samaria to confirm the genuineness of some Samaritans’ conversion to Christianity (Acts 8).
Years later John apparently moved to Ephesus, where he established his ministry among the churches of western Asia Minor. Near the end of his life, John was exiled to the island of Patmos off the coast of Asia Minor, and there he wrote the book of Revelation, a vision of the final days of the world.
While John’s title as “the disciple whom Jesus loved” certainly sets him apart as one who enjoyed a special relationship with Jesus, all believers in a sense can also claim this privileged title, for we are all followers (disciples) whom Jesus loves.
