Please read Jerry Bridges, "Gospel-Driven Sanctification"
"No sin can be crucified either in heart or life unless it first be pardoned in conscience.... If it be not mortified in its guilt, it cannot be subdued in its power." William Romaine
Here is some great theology.
The Bible is far more than a rulebook to follow. It is primarily the message of God's saving grace through Jesus Christ, with everything in Scripture before the cross pointing to God's redemptive work and everything after the cross--including our sanctification--flowing from that work.
There is no such thing as justification without definitive sanctification. They both come to us as a result of Christ's work for us.
Gradually over time, and from a deep sense of need, I (Jerry Bridges) came to realize that the gospel is for believers, too. When I finally realized this, every morning I would pray over a Scripture such as Isaiah 53:6," All we like sheep have gone astray; we have turned every one to his own way; and the Lord has laid on him the iniquity of us all," and then say, "Lord, I have gone astray. I have turned to my own way, but you have laid all my sin on Christ and because of that I approach you and feel accepted by you."
I came to see that Paul's statement in Galatians 2:20, "The life I now live in the flesh I live by faith in the Son of God who loved me and gave himself for me," was made in the context of justification (see vv. 15-21). Yet Paul was speaking in the present tense: "The life I now live ...." Because of the context, I realized Paul was not speaking about his sanctification but about his justification. For Paul, then, justification (being declared righteous by God on the basis of the righteousness of Christ) was not only a past-tense experience but also a present-day reality.
And very importantly it (sanctification) involves a desperate dependence on Christ for the power to do these things, for we cannot grow by our own strength.
We must always keep focused on the gospel because it is in the nature of sanctification that as we grow, we see more and more of our sinfulness. Instead of driving us to discouragement, though, this should drive us to the gospel.
