I dont' know whether this line of conversation can go anywhere. It may stall out at the first word. The replies I have gotten suggest that, in the ears of my readers, "salvation" means something "abstract, theoretical, and distant" -- maybe having to do with the afterlife -- and that is by and large not relevant or of concern.
I just need to note that has not been my experience. I have had times of moral and spiritual lostness in which salvation was a "gracious light" a "homecoming," "a hearth of consolation," a sense of coming back to my true self.
A real life metaphor: I was nearly killed by a piece of barbecue chicken not long ago. It went down wrong and I was choking, unable to breathe. A friend at the table did the blessed Heimlich manuever so I am still here. For those moments I could not get my breath, salvation was breath (pneuma, spirit) -- not something distant or theoretical. And I assure you, I have had times of moral and spiritual choking, when life went down wrong, that made me far more desperate for salvation than that piece of chicken.
So all that said, what about "grace?" The word comes from the Greek "charis" meaning a gift. Back when I thought salvation was judicial, I thought grace was the merciful spirit that commuted my sentence. It really is that, but if salvation is something larger than forgiveness, then grace has to be larger too.
Everything is gift. There is creative grace that means there is something rather than nothing becaue God is generous. There is prevenient grace -- the awarenes of a need for God, the God-shaped hole in the human heart is a grace.
So if salvation is something larger than a commuted sentece, something that makes us whole (remember I am not making this up, it's what the word literally means), how is grace involved in that. How does grace grow us into what we were intended to be? How is our very self a grace? How is grace moving in our lives now to form us anew into the likeness of Christ? Into our own unique expression of God as Rahner would put it?
