My favorite quiet time with the Lord is all day long while I work outside. He has blessed me with the mantainance of some of His creation, and He whispers to me while I tend to the chores He has given me.
The best days are when I don't get in too much of a hurry in the morning, and I take time to say "good morning" to the Lord. I love mornings. (but I'm kinda strange that way; I rejoice in paying taxes and serving on jury duty as well, lol). Mornings are like Springtime; the birth of a new day full of God's wonders.
I do need to work on quiet time with Him in regards to my wife and me together praying. We have some sweet times when we remember to do that, but it still has not become a good habit yet.
Thanks for the question David, it made me think about it, and now I can make some positive steps to improve!
