It is easy to deny what is in the hearts of men, since we cannot see into the hearts of men. At least not directly.
It's interesting to me that the Church office building is the second tallest building in Salt Lake (by only 2 feet) second to Wells Fargo Bank.
"Because of pride, and because of false teachers, and false doctrine, their churches have become corrupted, and their churches are lifted up; because of pride they are puffed up." (2 Ne. 28: 12)
Or that the conference center is the largest auditorium on the planet. (https://www.lds.org/liahona/2005/08/news-of-the-church/tabernacle-choir-getting-to-know-unique-conference-center?lang=eng&_r=1)
"And it came to pass that I saw and bear record, that the great and spacious building was the pride of the world; and it fell, and the fall thereof was exceedingly great. And the angel of the Lord spake unto me again, saying: Thus shall be the destruction of all nations, kindreds, tongues, and people, that shall fight against the twelve apostles of the Lamb." (1 Ne. 11:36)
Did you know that the number one cause of death in the U.S. is heart disease?
"And all things shall be in commotion; and surely, men’s hearts shall fail them; for fear shall come upon all people."(D&C 88:91)
When I came home from my mission, as my plane descended into Salt Lake, I couldn't anything except for mountain tops and a few columns of smoke coming out of the smog.
"Yea, it shall come in a day when there shall be great pollutions upon the face of the earth; there shall be murders, and robbing, and lying, and deceivings, and whoredoms, and all manner of abominations; when there shall be many who will say, Do this, or do that, and it mattereth not, for the Lord will uphold such at the last day. But wo unto such, for they are in the gall of bitterness and in the bonds of iniquity. Yea, it shall come in a day when there shall be churches built up that shall say: Come unto me, and for your money you shall be forgiven of your sins.
O ye wicked and perverse and stiffnecked people, why have ye built up churches unto yourselves to get gain? Why have ye transfigured the holy word of God, that ye might bring damnation upon your souls? Behold, look ye unto the revelations of God; for behold, the time cometh at that day when all these things must be fulfilled. Behold, the Lord hath shown unto me great and marvelous things concerning that which must shortly come, at that day when these things shall come forth among you.
Behold, I speak unto you as if ye were present, and yet ye are not. But behold, Jesus Christ hath shown you unto me, and I know your doing. And I know that ye do walk in the pride of your hearts; and there are none save a few only who do not lift themselves up in the pride of their hearts, unto the wearing of very fine apparel, unto envying, and strifes, and malice, and persecutions, and all manner of iniquities; and your churches, yea, even every one, have become polluted because of the pride of your hearts. For behold, ye do love money, and your substance, and your fine apparel, and the adorning of your churches, more than ye love the poor and the needy, the sick and the afflicted.
O ye pollutions, ye hypocrites, ye teachers, who sell yourselves for that which will canker, why have ye polluted the holy church of God? Why are ye ashamed to take upon you the name of Christ? Why do ye not think that greater is the value of an endless happiness than that misery which never dies—because of the praise of the world? Why do ye adorn yourselves with that which hath no life, and yet suffer the hungry, and the needy, and the naked, and the sick and the afflicted to pass by you, and notice them not? Yea, why do ye build up your secret abominations to get gain, and cause that widows should mourn before the Lord, and also orphans to mourn before the Lord, and also the blood of their fathers and their husbands to cry unto the Lord from the ground, for vengeance upon your heads? Behold, the sword of vengeance hangeth over you; and the time soon cometh that he avengeth the blood of the saints upon you, for he will not suffer their cries any longer."(Mormon 8)
Maybe we can't see into the hearts of individuals. I know courageous people with unhealthy hearts, humble people who work in tall buildings, and pure people who live in filthy societies. These people seem to be exceptions though.
So that's one way to hear the "voice" of God.
