Brigham had a testimony of the Bible and the Book of Mormon. “Believe what is recorded in the Holy Bible concerning God and his revelations to the children of men . . . then you will know that the Book of Mormon is true.”
Joseph Smith’s influence remained with Brigham all his life. “I feel like shouting Hallelujah, all the time, when I think that I ever knew Joseph Smith, the Prophet whom the Lord raised up and ordained, and to whom he gave keys and power to build up the Kingdom of God on earth.” “The honest-in-heart ran together and gathered around him [Joseph] and loved him as they did their own lives.”
“I know that [Joseph Smith] was called of God, and this I know by the revelations of Jesus Christ to me, and by the testimony of the Holy Ghost.”
Brigham Young devoted his life to the gospel. He believed prayer would lead to a testimony of all truth. He knew that salvation depended on the Lord Jesus Christ through the Atonement. He had a strong testimony that the Bible and Book of Mormon were true. He loved the Prophet Joseph Smith and tried to follow his example of dedication to Heavenly Father.
