Thank you for the link. I did read most of this one page. I think if makes the simplicity of the Gospel of Grace much too complicated. However, as a person who was once taught of the mixture of grace and law for salvation I will agree that when we witness to an unbeliever we need to explain things much better than some do.

We also need to remember that when one is taught a mixture of law and grace for salvation that they believe (in most cases) that the "works" in Eph. 2:9 is referring to righteous deeds. In other words, they believe that they are saved by grace, through faith, not by righteous doings that are of themselves, so they cannot boast in their good deeds, but that it does not include obeying the Law. Thus making it possible to lose salvation.
