"that by his pen he could best serve the cause of reform, he desired to find a quiet retreat for study, and there, through the press, instruct and build up the churches. But Farel's solemn admonition came to him as a call from Heaven, and he dared not refuse. It seemed to him, he said, “that the hand of God was stretched down from heaven, that it lay hold of him, and fixed him irrevocably to the place he was so impatient to leave.”— D'Aubigne, History of the Reformation in Europe in the Time of Calvin, b. 9, ch. 17. GC 233.3"
"But the Lord said unto him, Go thy way: for he is a chosen vessel unto me, to bear my name before the Gentiles, and kings, and the children of Israel:"
Both passages describe a divine call to service that the individual initially hesitates to accept. While Acts 9:15 is a direct command, the EGW passage describes Farel's admonition as a call from Heaven, which Calvin ultimately accepts.
