Here's an older article in Modern Reformation by Rod Rosenbladt in on how some views of sanctification destroy confidence in our once-for-all salvation by grace...
What should the Christian do if he is reading the law and says, "This is not yet true of me: I don't love God with all my heart, and I certainly don't love my neighbor as I love myself. In fact, just today I failed to help a poor man on the side of the road who was having car trouble. I must not yet be a Christian." The answer of the Higher Life movement to the struggling Christian is, "Surrender more!" or, "What are you holding back from the Lord?"
The Reformation answer is different: "You hurry back to the second use of the law and flee to Christ where sanctification is truly, completely, and perfectly located." After this experience, the believer will feel a greater sense of freedom to obey (thus fulfilling the third use of the law), and this is the only way that one will ever feel free to obey. The most important thing to remember is that the death of Christ was in fact a death even for Christian failure. Christ's death saves even Christians from sin. There is always room at the cross for unbelievers, it seems. But we ought also to be telling people that there is room at the cross for Christians, too.
