'Salvation' in the Bible

Are they not all ministering spirits, sent forth to minister for them who shall be heirs of salvation?

How shall we escape, if we neglect so great salvation; which at the first began to be spoken by the Lord, and was confirmed unto us by them that heard him;

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

And being made perfect, he became the author of eternal salvation unto all them that obey him;

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

So Christ was once offered to bear the sins of many; and unto them that look for him shall he appear the second time without sin unto salvation.
