I never said that justification hasn't happened, we receive eternal life, forgiveness of all past, present and future sins at the moment God regenerates us. We are liberated from bondage to sin, but we still struggle with it because we still live in corrupt bodies of death. There's a big difference between serving sin and going to war against it. As soon as God regenerates us we enter into a mortal war against our flesh, in which we will suffer many losses.
