Gospel of Mark 3.13-21

“And he went up on the mountain and called to him those whom he desired, and they came to him. And he appointed twelve (whom he also named apostles) so that they might be with him and he might send them out to preach and have authority to cast out demons”. 
How Christ did chose His desciples, where did they preach and how did they end up their earthly life? Father Markos Mangasaryan provides explanations.
