The singer seems to find themselves without proper peace and a desperation for something more, a proper saviour: “peace in your violence and I’m in need of a saviour”.
In the Bible we read of Zacchaeus, a tax collector. He seems to have tried finding security for himself in money, yet when he encounters Jesus, he realises that money cannot be his saviour, only Christ can. Jesus came to seek and save the lost (Luke 19:10 – http://bit.ly/1QiQ8KK).
Remember Jesus came to be your saviour (and everybody else’s saviour) and will continually save you from sin.
