Wherefore, I command you again to repent, lest I humble you with my almighty power; and that you confess your sins, lest you suffer these punishments of which I have spoken, of which in the smallest, yea, even in the least degree you have tasted at the time I withdrew my Spirit.

I think we have all experienced that kind of flatness of sin.  But this verse is particularly poignant for me because of a very brief and pointed withdrawal I experienced in answer to a prayer.

Repentance is the theme of D&C 19.

Then there is this:

And of tenets thou shalt not talk, but thou shalt declare repentance and faith on the Savior, and remission of sins by baptism, and by fire, yea, even the Holy Ghost.

32 Behold, this is a great and the last commandment which I shall give unto you concerning this matter; for this shall suffice for thy daily walk, even unto the end of thy life.

General Conference is the way it is for a reason, my biddies.  But also notice the word ‘tenets.’  Tenets . . . like creeds?  It may be that a creedal Christian who is really interested in homoouisia or whatever foofara is doing just fine if he is praying and repenting and such.  I don’t think false doctrine is harmless for any of us, it will have to be sorted out sooner or later, but for some people later is fine.
