1thess5vv16-18

Never stop - whatever happens.

Reminded of the words from the old song 'Paul and Silas were in jail, no one there to pay the bail...' (acts16vv22-25).
I recall an old preacher asking "Why are you under the circumstances?..."!
Paul lived what he preached.

phil4vv6-7

Don't be anxious - pray with thanksgiving.

See similar 'Pray with rejoicing and thanks' section above - written to the Philippians.
On his first visit to Philippi Paul had been unceremonously thrown into jail.
Were jailer and former fellow prisoners part of the church written to?

1tim2vv1-3

That we may lead a quiet and peaceable life in all godliness and reverence.

Not giving God a list of how we could do a better job than they...
Not plotting a coup...
Instead he says 'ask God to help and bless them - and be thankful for them'.

Paul was involved in an incident at Philippi when he received unlawful (beat up first, ask questions later) treatment from those in authority ( (acts16vv22-25)).
We know he prayed - but no details of the content. Are we safe to assume he practiced what he preached?
