David Jeffries, giving the album four stars at AllMusic, writes, "the rapper deliver the goods on this awesome debut."[1] Signaling in a four star review by CCM Magazine, Grace S. Aspinwall realizes, "Raw, gritty, and enigmatic, this project from the ultra-talented newcomer NF, is an impressive effort", and calls NF "an artist to watch, and brilliance is sure to follow this beautiful, sometimes dark, and vulnerable project."[2] Specifying in a five star review for Jesus Freak Hideout, Kevin Hoskins responds, "The only downfall here will be that some people aren't impressed by such raw, personal, and emotionally-driven rap, but that's exactly what makes this stand out among so many rap albums out today... This has 'album of the year' written all over it."[4] Steve Hayes, delivering a ten out of ten review at Cross Rhythms, regards this as, "unquestionably one of the finest ever to emerge from the gospel hip-hop scene."[3]
