With a Twinkle in His Eye, Mormon 8:31

"I remember years ago when I was a bishop I had President Heber J. Grant talk to our ward. After the meeting I drove him home. … Standing by me, he put his arm over my shoulder and said: ‘My boy, you always keep your eye on the President of the Church and if he ever tells you to do anything, and it is wrong, and you do it, the Lord will bless you for it.’ Then with a twinkle in his eye, he said, ‘But you don’t need to worry. The Lord will never let his mouthpiece lead the people astray.’” (Conference Report, October 1960, p. 78.)

"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." - Mormon 8:31
