I think that just about says it all. Surrender is looked at these days as a bad word, but in God’s economy it’s the best way to live To give up all expectations and preconceptions and to let God be God and do what He does best is freeing in the utmost.
I don’t subscribe to the philosophy of “let go and let God” as much as you do your part in obedience and surrender the outcome to God. Most of obedience is surrender, but there is also an aspect of getting yourself ready to receive what God has for you.
As much as you trust God, the more you will surrender to God. The more you know of God, the more you will trust God. The more you surrender, you will trust God. The more you surrender to God, the more you will know God. It’s all interconnected.
Surrender and trust is the key. Then when your expectations are completely centered on God, great things happen.
