That passage simply describes common grace. God doesn't rain down fire on unbelievers, but lets them live on alongside believers. In this way, he is the savior of all men...but the the special saving grace is only given to "those who believe."

[Canticle_of_Deborah]

There is no mention of grace there. Where do you get that? It's not there is the passage at all.

Your opinions sound dangerously like personal interpretation of Scripture. This was specifically warned against IN Scripture:

2 Peter 3:15-16 So also our beloved brother Paul wrote to you according to the wisdom given him, 16 speaking of this as he does in all his letters. There are some things in them hard to understand, which the ignorant and unstable twist to their own destruction, as they do the other scriptures.
