Pay close attention to yourself [concentrate on your personal development] and to your teaching; persevere in these things [hold to them], for as you do this you will ensure salvation both for yourself and for those who hear you.

Fight the good fight of the faith [in the conflict with evil]; take hold of the eternal life to which you were called, and [for which] you made the good confession [of faith] in the presence of many witnesses.
