Sometimes when I don't fall asleep right away at night I find myself thinking about things (and people) I can't control. It doesn't help to just lie there. So I get up. Usually I can go back to bed and fall asleep after I've been up awhile... but usually during that time of being awake God gets through to me, gently, turning my attention away from the faults of others and to my personal relationship with Him. Sometimes I even get some things done when I'm awake like this, but the best is what God gets done in me.
