By which also ye are saved, if ye keep in memory what I preached unto you, unless ye have believed in vain.

by which also ye are saved, if ye hold fast the word which I preached unto you, except ye believed in vain.

and by means of which you are being saved. I would like to remind you of the words that I used in telling it to you, since you are still holding fast to it, and since it was not in vain that you became believers in Christ.

durch welches ihr auch errettet werdet (wenn ihr an dem Worte festhaltet, das ich euch verkündigt habe), es sei denn, daß ihr vergeblich geglaubt habt.

Por el cual asimismo, si retenéis la palabra que os he predicado, sois salvos, si no creísteis en vano.

Pelo qual também sois salvos, se retiverdes a palavra naquela maneira, em que eu vos tenho anunciado; a não ser se tenhais crido em vão.

É por este Evangelho que sois salvos, desde que segureis firmemente a palavra que preguei, a menos que tenhais crido em vão.
