Skillet - Collide Lyrics Meaning

From the christian perspective, this song is about the tough fight with the World, see the entirety of verse 1.
The chorus is about "Something", most likely implying Jesus "that keeps my faith alive" through all the hard times in my life(rephrased a bit).
Verse 2. "We are healing, but it(Sin?)'s killing us inside"
"Can we take a chance, when faith and fear collide?". Doubting if you can hold on, I guess.
