There is an old song by the band “Degarmo and Key” called “Casual Christian”. The beginning of the song says, “I don’t want to be a casual Christian / I don’t want to lead a lukewarm life / ‘Cause I want to light up the night / With an everlasting light / I don’t want to lead a casual Christian life.” Though the song is over twenty-five years old, the lyrics still regularly play in my mind. Put simply, this is the call of my life, and I believe it is the call for every disciple of Jesus.
Casual Christianity is mediocre Christianity. It is lukewarm Christianity. It is nothing more than religious busyness, and it very literally makes God sick (Revelation 3:16).
