Being a servant is not a role as much as it is an attitude. Being a servant is not about groveling at the feet of the Master. Much more, it is an attitude of the heart. Jesus was calling us to a state of being, not a role in society.
What Jesus is calling us to do is to root out sin in our lives at its very core. He is calling us to more than a recitation of a grocery list of sins in a confessional. He is calling us to a deep introspection of why we do the things we do.
