Millennial Messiah, The Second Coming of the Son of Man, pg. 2; “The Church of Jesus Christ of Latter-day Saints, which is the kingdom of God on earth—the kingdom designed to prepare men to sit down with Abraham, Isaac, and Jacob…—has been set up among men; and to all the citizens of the kingdom…” – Bruce McConkie

Luke 17:20-21; “And when he was demanded of the Pharisees, when the kingdom of God should come, he answered them and said, The kingdom of God cometh not with observation: 21 Neither shall they say, Lo here! or, lo there! for, behold, the kingdom of God is within you.”

According to Jesus the Kingdom of God is already here for people – long before Mormonism came on the scene.
