Alma 5

 Alma spoke of those that - 

"...humble themselves and do walk after the holy order of God, wherewith they have been brought into this church, having been sanctified by the Holy Spirit, and they do bring forth works which are meet for repentance—"  (Alma 5:54)

I specifically noticed "they do bring forth works which are meet for repentance".  It suggests to me that we not only confess and repent, but that we bring forth work that is evidence of repentance.
