Jesus first visited Arlin when he was 18, while at college, preparing to go on a mission. His desire to get right with God is what brought this about. Details are in The Christian Writings & Testimonies of Arlin Ewald Nusbaum.

As a missionary, Arlin was called to intercede on His behalf in spreading the Good News and calling the wicked to repent. Then, after his mission, to bring doctrinal errors to light and correct historical errors as well (see pages Church and Israel).
