Here are three that come to mind.
^"Oceans (Where Feet May Fall)" by Hillsong United.
"Spirit lead me where my trust is without borders." <- Salvation is a spatially infinitely value, consistent with LII.
^"Salvation is Here" by Hillsong United.
Simply a great song about salvation. Very emotivist.
^"You Are My Salvation" by Martin Smith.
Relaxing song about merry attachments.
Some songs that are not about salvation:
"Salvation" by The Cranberries is about a clown. "Salvation" by The Strumbellas is about a madman looking for love. "Save Me" by k.d. lang is about the soul.
Thank you.
