Remembrance and Dependence

I'm reading in Isaiah 51.10 today where Isaiah calls God to remember his past deeds; specifically to the crossing of the Red Sea—this seems to be the key event to look back on and see God's deliverance for God's people. Isaiah is calling God to remember his great deliverance "a way for the ransomed to pass over" he puts it, and to act again in the same way on behalf of his people.

It's a huge lesson for us. Calling God to remember the great works that he has already done for his people is a way of expressing our dependence upon him and asking him to do the same work on behalf of his people again.
