'Salvation' in the Bible

Are they not all ministering spirits, sent out to render service for the sake of those who will inherit salvation?

how will we escape if we neglect so great a salvation? After it was at the first spoken through the Lord, it was confirmed to us by those who heard,

For it was fitting for Him, for whom are all things, and through whom are all things, in bringing many sons to glory, to perfect the author of their salvation through sufferings.

And having been made perfect, He became to all those who obey Him the source of eternal salvation,

But, beloved, we are convinced of better things concerning you, and things that accompany salvation, though we are speaking in this way.

so Christ also, having been offered once to bear the sins of many, will appear a second time for salvation without reference to sin, to those who eagerly await Him.

By faith Noah, being warned by God about things not yet seen, in reverence prepared an ark for the salvation of his household, by which he condemned the world, and became an heir of the righteousness which is according to faith.
