I don't think anything I've written recently is different than anything I've written in the past.
My sense of IF a person would EARN his way into heaven, IF he perfectly kept the law is based on Rom 2:13 and its context. There's no secret there. Besides, it's the accurate interpretation.
If Jean Chauvin lived a perfect life, which he hasn't, WOULD He have earned his way into heaven? Yes.
Call that "plan b" if you wish. The point remains that it IS a way of salvation....just NOT an effective one.
On reflection, there is a nuance in the word "salvation." I could see making that sentence "the point remains that it IS a method for achieving eternity."
"Way of Salvation" suggests that someone else assists. In this we're talking about someone perfectly "doing" the law of God, and therein, earning their own way into heaven.
