Ephesians 3:14-21 is my all-time favorite prayer. It's a breakthrough prayer filled with faith and expectancy in the God who is able to immeasurably more than we have ever asked for or could ever imagine. But before Paul gets to the prayer. He sets the context when he says, "I am asking that you not lose heart..."
Do not lose heart. Don't quit. Don't give up. I know it's hard, but breakthrough is coming, because we have a breakthrough God. If you are going through a hard chapter in your story. Let this encourage you; let it fill up your heart. God is the God of breakthrough!
