My two-cents worth:
I am saved not because I do good works,
I do good works because I am saved!
If you think about it, if one is trying to do good works to gain salvation, then that person is really doing it for him/herself because they are trying so desperately to save his/her own life. But on the other hand, one will do good works because God has saved (via Christ) him/her from eternal death and so therefore, the work is for God and His Glory.
In His Name,
