Is Sanctification Needed Before Salvation?

As a believer I was always taught that we get saved by what we believe, and some time later the Holy Spirit would clean us up and do the work sanctifications in us. They say you had to catch a fish before you could clean it. But is that what the Scriptures teach? Is that what Jesus taught? Is repentance necessary for Salvation, or is it something that happens later? The Church so tenaciously protects salvation by grace apart from all works that they have, as I see it, gone into error. But you decide for yourself, I have put together a study book that will lay it out in front of you, with the Scriptures to prove any points taken. You will rethink what it means to be saved when you read this book.
