'Salvation' in the Bible

For I have known that this shall fall out to me for salvation, through your supplication, and the supply of the Spirit of Christ Jesus,

and not terrified in anything by those opposing, which to them indeed is a token of destruction, and to you of salvation, and that from God;

So that, my beloved, as ye always obey, not as in my presence only, but now much more in my absence, with fear and trembling your own salvation work out,
