Today's reading in the...Reading the bible... thread above in the stickies is 1 Timothy 4 . The last two verses are ;

15 Be diligent in these matters; give yourself wholly to them, so that everyone may see your progress. 16 Watch your life and doctrine closely. Persevere in them, because if you do, you will save both yourself and your hearers.

So what is Paul encouraging us persevere in to save ourselves and others ? Why should we be careful of ideas presented to us by others ? Has Paul given us advice of 'who' we should be in another supporting chapter in 1 Timothy ? What is doctrine and why is it so important ?
