Impressions are Impressions!

Here is a great passage from "Decision Making and the Will of God by Garry Freisen. I think it's possible that "God's inward peace leading us" just may be an unbiblical lie that many people (and I have believed it in the past) believe. I haven't really seen anyone back it us scripturally though, besides taking a verse out of context. I'd love some response. I know this is a touchy subject for people and don't want to claim to have the corner on truth, but I would really like for someone to show me why we can make decisions based on some inner feeling of peace.

Chapter 8
"since peace is a fruit of the Spirit (Galatians 5:22), it is viewed by many as one of the means at His disposal to communicate His will to the believer.

This concept is based primarily on the exhortation of Colossians 3:15 "And let the peace of Christ rul in your hearts..." The explanation is that this peace functions as an umpire that "calls" each decision in question. So long as the believer is living within the center of God's will, he experiences and inner quietness of heart "which surpasses all comprehension" (Philippians 4:7). Through this peace the Umpire is calling "Safe!" But if the Christian begins to move in the wrong direction, he experiences increasing restlessness and inner anxiety--an indication that he is about to step "out of bounds."
It is not difficult to see the logic of this explanation, and it corresponds beautifully with the other aspects of the traditional view of guidance. Unfortunately, it dos not correspond with the rest of the passage of which it is a part, and we suspect that the apostle Paul would be surprised to learn that his statement to the Colossians was being explained in such a way. For he was not writing about God's provision for decision making, but rather a moral lifestyle that is consistent with the believer's position in Christ.
The statement "let the peace of Christ rule in your hearts" is part of a paragraph that runs from verses 12 through 17 in Colossians 3. That paragraph begins with an exhortation for believers to "put on" certain virtues: compassion, kindness, humility, gentleness, patience, forbearance, forgiveness, and above all, love, "which is the perfect bond of unity"(3:14). These virtues are to replace discarded vices such as immorality, greed, anger, abusive speech, lying, and the like (3:5-11)...Rather Christians are to be characterized by unity--a unity that will grow spontaneously as Christians put on the garments of love (3:12-14), submit to the peace of Christ (3:15), share the word of Christ (3:16), and do all things with thanksgiving in the name of the Lord Jesus (3:17).
