Are you a saviour?

Whilst listening to a series of sermons preached on the book of Obediah I was distracted by the last verse,

"And saviours shall come up on mount Zion to judge the mount of Esau; and the kingdom shall be the Lord's".

I first thought how can there be saviours in the plural, I only know one Saviour? ... Well look at James 5v19&20,

"Brethren, if any of you do err from the truth, and one convert him; let him know, that he which converteth the sinner from the error of his way shall save a soul from death, and shall hide a multitude of sins."

and 1 Timothy 4 v16,

"Take heed unto thyself, and unto doctrine: for in doing this thou shalt both save thyself and them that hear thee."

Does this mean that we can be saviours in the sense that our walk and our attention to the doctrines of Christ will be used of God in the salvation of others?
I find this an encouragement to keep on praying for those lost souls who have a place in my heart.
