'Salvation' in the Bible

Are they not all ministering spirits, sent forth to do service for the sake of them that shall inherit salvation?

how shall we escape, if we neglect so great a salvation? which having at the first been spoken through the Lord, was confirmed unto us by them that heard;

For it became him, for whom are all things, and through whom are all things, in bringing many sons unto glory, to make the author of their salvation perfect through sufferings.

and having been made perfect, he became unto all them that obey him the author of eternal salvation;

But, beloved, we are persuaded better things of you, and things that accompany salvation, though we thus speak:

so Christ also, having been once offered to bear the sins of many, shall appear a second time, apart from sin, to them that wait for him, unto salvation.
