The 12 apostles who followed Jesus Christ included Peter, Andrew, James, John and Philip. Bartholomew, Matthew, Thomas, James the son of Alphaeus and Simon the Zealot were also disciples. Two disciples were named Judas: Judas the son of James and Judas Iscariot who betrayed Jesus Christ.
Jesus Christ chose 12 disciples who lacked any exceptional scholarly or rabbinical background. The disciples made up a rag-tag group of ordinary men who included fishermen, tax collectors and would-be revolutionaries. Jesus took them alongside him in his ministry, immersing them in his teachings and sending them out to be his witnesses.
The Bible chronicles the fallibility of the 12 disciples, highlighting the humanity and struggle of these men who were following their messiah. For instance, Peter denied Jesus when pressured by townspeople, Thomas doubted the claims that Jesus had risen from the dead, and Judas sold out Jesus for a bag of silver coins.
While filled with faults and shortcomings, these apostles changed the world by following Christ's command to preach the gospel throughout the nations. After the crucifixion, the apostles went as far as Persia, Ethiopia and Syria to bring Christ's message, with many of them suffering greatly and subsequently becoming martyrs for the cause.
