'Salvation' in the Bible

Are not all angels spirits that serve Him--whom He sends out to render service for the benefit of those who, before long, will inherit salvation?

how shall *we* escape if we are indifferent to a salvation as great as that now offered to us? This, after having first of all been announced by the Lord Himself, had its truth made sure to us by those who heard Him,

and so, having been made perfect, He became to all who obey Him the source and giver of eternal salvation.

But we, even while we speak in this tone, have a happier conviction concerning you, my dearly-loved friends--a conviction of things which point towards salvation.

so the Christ also, having been once offered in sacrifice in order that He might bear the sins of many, will appear a second time, separated from sin, to those who are eagerly expecting Him, to make their salvation complete.
