"One of the best parts of Rock School of Ministry is the perspectives you get from such amazing teachers who walk in Holy Spirit! As an example, you will receive teachings from an apologetic in one class and an empath in another or an evangelist in one and a prophet in the next; RSOM exemplifies Ephesians 4:16 and 1 Corinthians 12:12 - we each were made of different parts but one body."

- Rachael, RSOM Alumni
