The Mormon Confirmation:



Trusting one’s eternal life on a so-called, Burning of the Bosom (Moroni 10:4-5; D&C 9:8)







Only a fool trust his own heart (feelings)



“Just pray about it, and the Holy Spirit will confirm Mormonism to you by causing a burning in your bosom,” says the rosy cheek bright eyed Mormon (LDS) missionary at your doorstep.

However, relying on one’s feelings (as with the so-called burning of the bosom as taught in the Book of Mormon,) can lead you to great error: “For there is a way that seems right to a man but in the end it leads to death (Prov. 16:25). Proverbs 28:26 clearly opposes the LDS so-called test of truth: “He that trusteth in his own heart is a fool: but whoso walketh wisely, he shall be delivered” (KJV). We must test doctrine by Scripture, not by feelings and emotion, which according to Scripture, is foolish.

The LDS rejects the Jesus Christ of biblical revelation in that they teach that Jesus is one of many Gods. One of the fundamental differences between Christianity and Mormonism is that the LDS Church teaches polytheism (i.e., the belief in many true Gods). Note for example some teachings from past LDS Apostles and Prophets including the founder and first Prophet of the LDS Church, Joseph Smith:
