If you wish to go where God is, you must be like God, or possess the principles which God possesses...Is not God good? Then you be good; if He is faithful, then you be faithful

‘I shall speak with authority of the Priesthood in the name of the Lord God. … Notwithstanding this congregation profess to be Saints, yet I stand in the midst of all [kinds of] characters and classes of men. If you wish to go where God is, you must be like God, or possess the principles which God possesses, for if we are not drawing towards God in principle, we are going from Him and drawing towards the devil. Yes, I am standing in the midst of all kinds of people.
“‘Search your hearts, and see if you are like God. I have searched mine, and feel to repent of all my sins.
“‘We have thieves among us, adulterers, liars, hypocrites. If God should speak from heaven, He would command you not to steal, not to commit adultery, not to covet, nor deceive, but be faithful over a few things. … Is not God good? Then you be good; if He is faithful, then you be faithful. Add to your faith virtue, to virtue knowledge, and seek for every good thing. The Church must be cleansed, and I proclaim against all iniquity.’”
