One must be careful about seeking a form of equilibrium with sin. If a person is devoted to Christ, then they acknowledge that sin has no comfortable place in their life.
Still, we often struggle with particular sins that seem most difficult for us to eradicate. In time, the continual cycle of sin and repentance wears us down.
While the repentance may seem genuine, we establish a kind of equilibrium with this sin. The equilibrium creates a false sense of comfort and thus we tolerate the presence of evil. This is a grave danger. There is no compromise with sin that does not lead to death.
