In a YouTube interview Morrison said he heard about Skillet looking for a new guitarist so he contacted his friend Tim Rosenau (guitarist for tobyMac) asking for more information. From there Rosenau asked tobyMac, however there was never a reply back from Rosenau. Later Morrison received an email from the Skillet's manager, Scotty Rock, asking for photos, certain songs, and Morrison's testimony. Later Morrison received a phone call from an area code he wasn't familiar with so he left the call alone but claimed he had a "felt led" to call back the number. The phone call led to the voice mail of Scotty Rock who later called back Morrison where John Cooper joined in on the conversation asking Morrison to fly out where he had only a week to prepare himself and learn the songs.
He is a sports fan. His teams are the NCAA's Ohio State Buckeyes, MLB's Cincinnati Reds, and NFL's Cincinnati Bengals. He's been a Christian since the age of seven along with his family being Christian as his parents had a Christian traveling group. Along with being a Christian, one of his favorite Bible verses out of a few is Romans 8:28. Along with a Psalm verse, Psalm 144:1 where it talks about the Lord preparing your hands and fingers for battle which Seth claims he finds cool because it relates to playing guitar. He also says that even before joining Skillet he had been a huge Skillet fan.
