Awarding the album five stars for New Release Tuesday, Kevin Davis says, "This is truly a moving and prayerful worship experience." Tony Cummings, giving the album a six out of ten review from Cross Rhythms, writes, "though this is a reasonable enough debut, to me it never truly sounds deserving of its bestselling status." Rating the album five stars at Louder Than the Music, Jono Davies describes, "Put this album on when you're sad, put this album when you're happy, and let the emotion of the songs draw you in and take you on a quiet and reflective journey around the musical world of Steffany Gretzinger." Logan Merrick, indicating in a 4.5 out of 5 review by Christian Music Review, states, "This whole album features song after song of authentic, pure, lyrical content." Signaling in a three and a half star review at 365 Days of Inspiring Media, Jonathan Andre writes, "The Undoing is great, and ought to be enjoyed thoroughly". Jessica Morris, awarding the album nine and a half stars for Jesus Wired, says, "Steffany Gretzinger's vocals are exquisite, and The Undoing allows them to shine brilliantly, largely due to the authentic and evocative worship created through the album."
