Lisp's general model is functional. It makes it easier for you to write in functional style, and is lots of fun. To be more practical, it allows assignments and other side effects, but their usage is discouraged, except for in some specially defined cases (global counters, for instance, which would be quite tedious w/o side effects).

Abelson and Sussman's book is terrific. As a part of a course, I did quite a lot of exercises in it, in Scheme and it was great.
