Is it farther or further?
c.1300, "one who delivers or rescues from peril," also a title of Jesus Christ, from Old French sauveour, from Late Latin salvatorem (nominative salvator) "a saver, preserver" (cf. Spanish salvador, Italian salvatore), from salvatus, past participle of salvare "to save" (see save (v.)). In Christian sense, a translation of Greek soter "savior." Replaced Old English hælend, literally "healing," noun use of present participle of hælan (see heal).
one who saves from any form or degree of evil. In its highest sense the word indicates the relation sustained by our Lord to his redeemed ones, he is their Saviour. The great message of the gospel is about salvation and the Saviour. It is the "gospel of salvation." Faith in the Lord Jesus Christ secures to the sinner a personal interest in the work of redemption. Salvation is redemption made effectual to the individual by the power of the Holy Spirit.
