The Word is not understood, except by those who are enlightened. The human rational faculty cannot comprehend Divine, nor even spiritual things, unless it be enlightened by the Lord (Arcana Coelestia 2196, 2203, 2209, 2654). Thus they only who are enlightened comprehend the Word (n. 10323). The Lord enables those who are enlightened to understand truths, and to discern those things which appear to contradict each other (n. 9382, 10659). The Word in its literal sense appears inconsistent, and in some places seems to contradict itself (n. 9025). And therefore by those who are not enlightened, it may be so explained and applied, as to confirm any opinion or heresy, and to defend any worldly and corporeal love (n. 4738, 10339, 10401). They are enlightened from the Word, who read it from the love of truth and good, but not they who read it from the love of fame, of gain, or of honor, thus from the love of self (n. 9382, 10548, 10549, 10550) They are enlightened who are in the good of life, and thereby in the affection of truth (n. 8694). They are enlightened whose internal is open, thus who as to their internal man are capable of elevation into the light of heaven (n. 10401, 10402, 10691, 10694). Enlightenment is an actual opening of the interiors of the mind, and also an elevation into the light of heaven (n. 10330). There is an influx of holiness from the internal, that is, from the Lord through the internal, with those who regard the Word as holy, though they themselves are ignorant of it (n. 6789). They are enlightened, and see truths in the Word, who are led by the Lord, but not they who are led by themselves (n. 10638). They are led by the Lord, who love truth because it is truth, who also are they that love to live according to Divine truths (n. 10578, 10645, 10829). The Word is vivified with man according to the life of his love and faith (n. 1776). The things derived from one's own intelligence have no life in themselves, because from man's proprium [or attributes] there is nothing good (n. 8941, 8944). They cannot be enlightened who have much confirmed themselves in false doctrine (n. 10640). It is the understanding which is enlightened (n. 6608, 9300)...

...The Word without doctrine is not understood (Arcana Coelestia 9025, 9409, 9424, 9430, 10324, 10431, 10582). True doctrine is a lamp to those who read the Word (n. 10401). Genuine doctrine must be from those who are in enlightenment from the Lord (n. 2510, 2516, 2519, 2524, 10105). The Word is understood by means of doctrine formed by one enlightened (n. 10324). They who are in enlightenment form for themselves doctrine from the Word (n. 9382, 10659). What is the difference between those who teach and learn from the doctrine of the church, and those who teach and learn from the sense of the letter of the Word alone (n. 9025). They who are in the sense of the letter of the Word without doctrine, do not come into any understanding concerning Divine truths (n. 9409, 9410, 10582). They may fall into many errors (n. 10431). They who are in the affection of truth for the sake of truth, when they become adults, and can see from their own understanding, do not simply abide in the doctrinals of their churches, but examine from the Word whether they be true or not (n. 5402, 5432, 6047) ...It is not the mark of a wise man to confirm a dogma, but to see whether it be true before it is confirmed; and that this is the case with those who are in enlightenment (n. 1017, 4741, 7012, 7680, 7950)...



An example of someone trying to interpret Bible prophecy using a private interpretation of the prophecies in the book of Daniel is William Miller, a Baptist preacher, who predicted that Jesus Christ would return to the earth during the year 1844.



   William Miller

The Great Disappointment was a major event in the history of the Millerite movement, a 19th-century American Christian sect that formed out of the Second Great Awakening. Based on his interpretations of the prophecies in the book of Daniel, William Miller, a Baptist preacher, proposed that Jesus Christ would return to the earth during the year 1844. The specific date of October 22, 1844, was preached by Samuel S. Snow. Thousands of followers, some of whom had given away all of their possessions, waited expectantly. When Jesus did not appear, the date became known as the Great Disappointment. Between 1831 and 1844, on the basis of his study of the Bible, and particularly the prophecy of Daniel 8:14—"Unto two thousand and three hundred days; then shall the sanctuary be cleansed"—William Miller, a Baptist preacher, predicted and preached the imminent return of Jesus Christ to the earth. He first assumed that the "cleansing of the sanctuary" represented purification of the earth by fire at Christ's Second Coming. Then, using an interpretive principle known as the day-year principle, Miller, along with others, interpreted a prophetic "day" to read not as a 24-hour period, but rather as a calendar year. Miller became convinced that the 2,300-day period started in 457 B.C. with the decree to rebuild Jerusalem by Artaxerxes I of Persia. Simple calculation revealed that this period would end—and hence Christ would return—in 1843. Despite the urging of his supporters, Miller never announced an exact date for the expected Second Advent. But he did narrow the time period to sometime in the Jewish year 5604, stating: "My principles in brief, are, that Jesus Christ will come again to this earth, cleanse, purify, and take possession of the same, with all the saints, sometime between March 21, 1843 and March 21, 1844." March 21, 1844, passed without incident. After the failure of Miller's expectations for October 22, 1844, the date became known as the Millerites' Great Disappointment. Hiram Edson recorded that "Our fondest hopes and expectations were blasted, and such a spirit of weeping came over us as I never experienced before... We wept, and wept, till the day dawn."[15] Following the Great Disappointment most Millerites simply gave up their beliefs. Some did not and viewpoints and explanations proliferated. Miller initially seems to have thought that Christ's Second Coming was still going to take place—that "the year of expectation was according to prophecy; but... that there might be an error in Bible chronology, which was of human origin, that could throw the date off somewhat and account for the discrepancy."[16] Miller never gave up his belief in the Second Coming of Christ; he died on December 20, 1849, still convinced that the Second Coming was imminent. Miller's legacy includes the Advent Christian Church with 61,000 members, and the Seventh-day Adventist Church with over 18 million members. Both these denominations have a direct connection with the Millerites and the Great Disappointment of 1844. (From Wikipedia)
