"Contend earnestly for the like precious faith with the Apostle Peter, 'and add to your faith virtue,' knowledge, temperance, patience, godliness, brotherly kindness, charity; 'for if these things be in you, and abound, they make you that ye shall neither be barren nor unfruitful in the knowledge of our Lord Jesus Christ.' Another point, after having all these qualifications, he lays this injunction upon the people 'to make your calling and election sure.' He is emphatic upon this subject—after adding all this virtue, knowledge, &c., 'Make your calling and election sure.' What is the secret—the starting point? 'According as His divine power hath given unto us all things that pertain unto life and godliness.' How did he obtain all things? Through the knowledge of Him who hath called him. There could not anything be given, pertaining to life and godliness, without knowledge....

"We have no claim in our eternal compact, in relation to eternal things, unless our actions and contracts and all things tend to this end. But after all this, you have got to make your calling and election sure. If this injunction would lie largely on those to whom it was spoken, how much more those of the present generation!

"1st key: Knowledge is the power of salvation. 2nd key: Make your calling and election sure. 3rd key: It is one thing to be on the mount and hear the excellent voice, &c., &c., and another to hear the voice declare to you, You have a part and lot in that kingdom." (Joseph Smith, HC 5:21)
