Hi,
The problem evangelicals have is one I have also encountered often in discussion.

It is this: We have often been so filled up with a theology of justification that we don't understand the theology of sanctification.

Pink was a man who understood both.

Simply stated the doctrine of sin goes like this:
1. Sin is breaking God's law.
2. Breaking law always has consequences.
3. The consequences of sin are twofold: Eternal and temporal, i.e. consequences before God's throne and consequences which we experience in this life. It is this distinction between eternal and temporal consequences that has been lost in recent times. Older theologians like Pink understood it.
4. The eternal consequences of sin are guilt before God's throne, spiritual death, broken fellowship with God and, eventually, eternal death (Hell). (There are probably others also but this is enough).
5. The temporal consequences of sin are what the Bible calls "death" (Rom 6 - "the wages of sin") and "destruction" (Gal 6:6-8). Wages are what we earn in time. These include things like personal brokenness, sickness, the fruit of the flesh, a contaminated conscience (the feeling of guilt), and so on. These are all things we experience in time.
6. When we come to Christ we are justified - our sins are forgiven - including the sins we haven't even committed yet. We don't lose justification simply because we sin after salvation. The eternal consequences of our sins are remitted in justification thus: our guilt is washed away, relationship with God is restored, we are born again spiritually and we will go to heaven when we die. This is a once for all eternity transaction
7. However when we come to Christ the temporal consequences of our sins are not removed. This is the province of sanctification.
The bottom line is this: sin is destructive. Every time we sin we sow destruction into our lives and we will eventually reap that destruction - in time! This is just as true for the Christian as it is for the non Christian. The point Paul is making about sowing and reaping in Gal 6 applies to Christians - that's who he is writing to and warning! So even though the eternal consequences of sin are fully dealt with at conversion and we never lose our justification even if we sin again after conversion; the temporal consequences of sin (destruction) still exist and we still, as Christians, will experience destruction if we sin.
The brokenness of sin in our lives needs to be removed and this is done progressively through sanctification. We need to re transformed back into the image of God, who is Christ. As a result the addict or alcoholic is probably still an addict the day after he gets saved. The man with a temper or other strong "fruit of the flesh" (Gal 5) still has it the day after he was saved. We still experience sickness, brokenness, pain even though we are Christians. These things are not removed at conversion but we remove them by sanctification through his blood and "dying daily".

It is this simple failure to understand the difference between the eternal consequences of sin and the temporal consequences of sin and the nature of justification and sanctification that causes much angst in the evangelical wing of the church.

Many are so full of justification that they have not understood sanctification.
