Jesus appoints the men he chooses to be his witnesses of who he is. These men, who are called apostles, will continue his mission, which is to preach about the power of the Kingdom of God. Those appointed by Christ are sovereignly chosen by him, which is evident in those whom he calls. These are fishermen, not the religiously elite. Moreover, most of these apostles will fade into obscurity but will be faithful apostles to bring about the message.
