Look. You can't even define "trinity" from the Bible. So we look to other sources for definitions. What specific text are you referring to? There is no one text that defines LS. There is actually a history of LS, but most recently defined by MacArthur and popularized by Paul Washer. That is why I refer to them. And that is why I google them.
I don't use Wikipedia often, but in this case it may prove to be a better source because it is neutral.
Here is their definition:
Note that it defines LS, and then gives the opposing view's objection to it. It is not something you find in the Bible.
The link is here:
http://en.wikipedia.org/wiki/Lordship_salvation
It gives a short history of this "doctrine."
That depends on your definition of it.
According to the definitions of MacArthur and Washer yes it is a works based salvation. Before their time no it wasn't. It has been redefined.
That article will show you how.
Whatever happened to sola fide? One cannot believe in LS and sola fide at the same time. A denial of sola fide in practice makes LS a heretical view. Would you agree with that? I never questioned salvation. One can believe in a heresy and still be saved. I believe that "speaking in tongues," as we know it today is a heresy, but I don't believe all in the Charismatic movement are unsaved.
There is a poster here that does not believe in the depravity of man. I don't believe in the Calvinistic view "Total Inability," but I do believe we all have a sin nature. But to believe that all are born totally innocent like Adam, IMO, is a heretical view. Yet I don't question that person's salvation. I could give many other examples.
I do understand progressive salvation. We are talking past each other.
We both have different views of LS. Until you come to an understanding of what is meant by LS, we will continue to speak past each other.
