None of us can ever be considered a true and faithful servant of God unless we repent. It is not a matter of us living without sin, none of us are able to accomplish that feat; it's a matter of us having faith in Jesus Christ and truly repenting of our sins as we strive to be the reflection of Jesus Christ that God calls on us to be! Christ says in Luke 5:32: "I have not come to call the righteous, but sinners, to repentance.”
