Mother Theresa was once asked: “How do you have a quiet time with God?”, she replied “I just sit and listen”.
I like that a lot! Can you just sit with God? We always want to fill our time with Him with something: A worship song, scripture, or a prayer list
So how to sit still: Yes, your thoughts may wonder, but just return your focus to being still. (This takes practice.) Use a word or short phrase to focus on. Something like: “Jesus” or “You’re a good, good Father.” Say it over and over in a thoughtful rhythm.
After a few times of practice, you will want to sit still more often with Your Father.
