Thank God for all He has done. One of the hardest things is to remember all He has done. This psalm takes the time to recall the stories of the past, and the faithful people of the past who have made big decisions for God. We need to remember the past, and all God has done – because this is the same God who is with us now. We can also write down or record all of the stories God is making in our lives now – so that we can remember His faithfulness when we are walking in the valley, and so that we can tell others of who He truly is.
