If you already believe that the Book of Mormon, like the Bible, is God's word, but you have doubts that the members of the Church of Jesus Christ of Latter-day Saints are literally under condemnation by Jesus Christ today for taking lightly the evil influence of the Secret Society as it exists today, please consider the following:
Rather than share opinions, it's best to stay with the scriptures to determine the truth according to God.
Doctrine & Covenants 84:54-57
54. And your minds in times past have been darkened because of unbelief, and because you have treated lightly the things you have received—
55. Which vanity and unbelief have brought the whole church under condemnation.
56. And this condemnation resteth upon the children of Zion, even all.
57. And they shall remain under this condemnation until they repent and remember the new covenant, even the Book of Mormon and the former commandments which I have given them, not only to say, but to do according to that which I have written—
At no time has any prophet of the church declared that this condemnation has been lifted.
Doctrine &Covenants 132:12-13
12. For there are many yet on the earth among all sects, parties, and denominations, who are blinded by the subtle craftiness of men, whereby they lie in wait to deceive, and who are only kept from the truth because they know not where to find it—
13. Therefore, that we should waste and wear out our lives in bringing to light all the hidden things of darkness, wherein we know them; and they are truly manifest from heaven—
The Lord in these verses has invited us to wear out our lives in bringing to light the hidden things of darkness. The root of all hidden things of darkness is Satan and his organization known as the secret society. We are not to just say but do according to that which is written.
3 Nephi 3:9
And behold, I am Giddianhi; and I am the governor of this the secret society of Gadianton; which society and the works thereof I know to be good; and they are of ancient date and they have been handed down unto us.
The Book of Mormon is an ancient record that repeatedly shares the battles between the secret society and the followers of Christ. The secret society calls themselves good, and they call that which is good evil.
