People who do pray generally don’t believe it’s futile. I pray a lot. I kinda “talk” to God throughout the day (and no I don’t get a letter as a reply lol) ... it helps ME. A lot. Often things that I wld like answered in one way don’t seem to get the result that I want ... but I’m ok with that because, (for me) I know God sees the big picture and what I want isn’t the same as what I need. Incidentally when I pray throughout the day it’s often just a few seconds, no more than a thought. Sometimes it will be about important stuff but often it will simply be Thanking God for random things such as seeing a beautiful tree, or how much happiness my dogs bring me. I “talk” to God without thinking about it: it’s just happens naturally. Again I want to emphasise that this is MY own feelings and like I said before everyone can choose how or even if they believe in anything at all. I just know for me I get so much comfort in my faith. I don’t know how I’d survive without believing in God as my saviour.
