second. William would also face different chronological periods that he would interpret using a
concordance. Soon, William would find the passage that would catch his attention, Daniel 8:14, a
verse that exposes the time period of 2300 days. After incessant study, William Miller concluded
that the 2300 days would have their fulfillment in 1843. Although at the beginning Miller had
doubts about putting dates on the return of Christ, when studying the Bible every day he was
convinced that his conclusion was correct.
Although the conclusions reached by Miller were reliable for him, he did not want to
preach them to the people, until one day God called him to preach them, and for that he had to
subdue William’s rebellion. The message about the second coming of Christ was delivered with
power by the providence of God. Little by little Miller’s studies were published in journals. His
fame ran throughout the United States and day after day his message was gaining followers.
Miller’s message was clear, if the earth was the sanctuary of God, which was to be purified with
fire, then Daniel 8:14 referred to the second coming of Christ. Taking as starting point the year
457 BC, the 2300 days would end in 1843, although Miller had pointed out the year, he had not
chosen a particular day. Among the followers that Miller had won was a group called “the
seventh month movement,” it was this movement who pointed out on October 22, 1844, as the
date for the second coming of Christ. Despite the great expectation, the day arrived, and it
passed, and Christ never came, and the Millerite movement was disappointed. William would
continue studying the Scripture in search of his error, while others continued to encourage him
not to falter in his research.
