Do Mormons Believe in Hell?

"The "heaven" the Mormon looks to and lives for is a real place of eternal progress, with endless association with loved ones, with families and friends. For those who are willfully indifferent to their opportunities on earth, the knowledge that they have fallen short of their highest possible happiness will be part of the penalty of the "hell" hereafter."
