What is the mainline Protestant understanding of "unceasing prayer"? The Bible speaks about this concept of unceasing prayer, to give some examples that seem to talk about thus:
1 Thessalonians 5:16-18 (Rejoice always, pray without ceasing, in everything give thanks; for this is the will of God in Christ Jesus for you.),

Other verses: Mark 13:32-37; Matthew 26:40-41;

I've heard Eastern-Orthodox priests as having  literal interpretation of this idea. Saying that we should follow the example of hermits, retreat in the wild and pray unceasingly.

I find that to be a bit extreme and wondered how do Lutherans, Reformed, Anglican and other mainline Protestants interpret these verses?
I suspect that differences of opinion might extend all the way to the individual level, rather than being settled upon by any particular denomination.

(So: what do you think it means?)

Inasmuch as I've grown up in the larger protestant tradition, I suppose my opinion might be worth more than nothing, so here goes: it sounds like an attitude to me; the continual practice of keeping short accounts with God, just another angle on loving God and loving your neighbor, just as Philippians 2 is an angle on the same.

I could be wrong, and I'm not a professional, so...
