It's interesting reading things you've learnt in the past, only to find you're relearning them again,... and again... and again.
I looked back at a couple of my posts from a year ago. In one I asked how often we have a lack of faith as to what God can do. Even though I've seen God at work in the past - in the Bible, in the lives of friends and others, and in my own life - I still have a lack of faith a lot of the time. It's when I look at my circumstances, and forget to thank Him for all His gifts, and for who He is that I lack faith.
So to my heart in that moment, God says, 'Be STILL and know that I am God' (Psalm 46:10).
