Final answer:
Jesus instructed the Apostles to go forth and make new disciples. This mission is central to the spread of Christianity and is documented in the New Testament Gospels.
Step-by-step explanation:
The instruction by Jesus to the Apostles was to go forth and make new disciples. This instruction is a pivotal part of the Christian faith, as it entails spreading the teachings of Jesus and expanding the community of believers. The term 'apostle' originates from the Greek word apostolos, meaning 'one sent, messenger, those sent by Christ to spread his teachings outside the Holy Land.' After Jesus' resurrection and ascension, his followers dispersed to fulfill this mission. The historical context of this directive involves the various sociopolitical groups within Jewish society at the time, such as the Sadducees, Pharisees, Essenes, and Zealots, each with their own interpretations of the laws and expectations of a messiah. The life and teachings of Jesus and the efforts of his apostles are chronicled in the New Testament Gospels: Matthew, Mark, Luke, and John.
