If I'm sitting or lying down, I like to close my eyes when I pray because it keeps me focused. If my eyes are open, I have a tendency to go 'off tangent' and wander off. (those dishes need to be washed...look at that floor!...what should I fix for dinner?)
But I also pray while working or driving and you should keep your eyes open when you do those things! ha! But its amazing how deeper I can get into prayer when my body is busy doing some kind of manual labor, and my mind is focused on Him.
And you are so right, Bondman! Informal is so much better!
Interesting! I wonder if females like to pray as they work more than males?
Cos God made you to be able to nicely multi-task (I suspect in order to be able to do half a dozen things at once with babies and children - or more!! *hehe*). Whereas we males he made us to be able to strongly and totally focus just on one thing - in the case of Australia's aboriginals to catch that large kangaroo, so that babies, children, women and men could eat!
My best ever time of praying was when I had a MAJOR need for a VERY serious prayer-answer from the Lord. I walked up and down the footpath of a busy road nearby. There were no pedestrians ('cept me!), and much noise from the passing cars. This was where I first learnt the amazing POWER of praying aloud!!
I prayed ALOUD as I walked, 5 or 10 minutes West, then back East again, some days for a very long time indeed, as I PERSISTED in prayer till He would answer. And like Fluffy said, 'tis fairly important to keep ones eyes open in situations like this! - so I also learnt to easily pray with eyes open.
I was many long weeks on that one, and finally did get a clear (but quite unexpected) answer from the Lord as to what I should do (persistence always pays of with Him!) - thereby taking my life into a dramatically new direction without which I'd certainly not be here with all you wonderful guys! OUR GOD IS INDEED GOOD!!
