Muffled
Jesus in me
A truly fulfilled prophecy was made by the Church of Jesus Christ of Latter Day Saint's founder Joseph Smith. This true prophet made a prophecy describing the American Civil War nearly 30 years before this historic war took place; this prophecy was totally fulfilled: :there will be a war between the northern states and the southern states beginning in South Carolina; the southern states will call upon Great Britain for assistance. Hence, this proves Joseph Smith was a true prophet.
