"In 1833 Miller received a license to preach, from the Baptist Church, of which he was a member. A large number of the ministers of his denomination also approved his work, and it was with their formal sanction that he continued his labors. He traveled and preached unceasingly, though his personal labors were confined principally to the New England and Middle States. For several years his expenses were met wholly from his own private purse, and he never afterward received enough to meet the expense of travel to the places where he was invited. Thus his public labors, so far from being a pecuniary benefit, were a heavy tax upon his property, which gradually diminished during this period of his life. He was the father of a large family, but as they were all frugal and industrious, his farm sufficed for their maintenance as well as his own. GC 332.1"
"What is my reward then? Verily that, when I preach the gospel, I may make the gospel of Christ without charge, that I abuse not my power in the gospel."
Both passages discuss the idea of a preacher not being a financial burden. Paul in 1 Corinthians 9:18 talks about preaching the gospel without charge, and the EGW passage describes Miller using his own funds and resources to support his ministry.
