Can anyone give me tips on how to have a prayer journal?
Sure, just make written notes of what you prayed about. Or do like I do, blog it in CF blogs. But be sure to not write personal info.
What is it for?
A prayer journal is useful so you can remember what you prayed, and kinda see where you are going. Journalling helps me focus, and give better quality prayers..more organized, and scriptural prayers, as I reflect on what I am saying, see the list of what I am asking, and even edit it. To journal gives me not just a way to remember, but a kind of conciousness and accountability of where I am and what how I am relating to God. Then after I pray, I can live my day, and after the day has transpired I can compare my thinking and my behavior during the day to what I prayed about earlier.
What do you write in it?
I write my exact prayers to God. I record what I actually think and want to say. Some people pray naturally, then write up notes afterwards, the high points of what they asked God for. I prefer to think pray and write at the same time.
How do you have one?
Use a the CF blog, is one way(again don't give personal details...you can think details, but don't write them). Or just write it up in MS Word.
