This song is from the early 1980s. Keith Green was a talented and popular pianist/singer/songwriter. Some people thought he was controversial because he spoke his mind. Those people just didn't like being challenged. The key line is "Use me Lord, glorify Your holy name through me". That's the way Keith lived his life. Sadly he didn't get to live it for very long; he died in a plane crash in 1982 at the age of 28.
