The work of the disciples was to spread a knowledge of the gospel. To them was committed the work of proclaiming to all the world the good news that Christ brought to men. That work they accomplished for the people of their time. To every nation under heaven the gospel was carried in a single generation.
The giving of the gospel to the world is the work that God has committed to those who bear His name. For earth’s sin and misery the gospel is the only antidote. To make known to all mankind the message of the grace of God is the first work of those who know its healing power.
