Optimism and faith

I was reading Hebrews 11 the other day, and it's a great, inspiring chapter about faith! I'm a pretty optimistic person, and I have big dreams. While some think one person can't do much, I refuse to let my passions and dreams die because of the monstrosity of the challenges. Hebrews 11 encourages me because it says and shows that by faith, we can do great things! 

Here's some snippets: "What is faith? It is the confident assurance that what we hope for is going to happen. It is the evidence of things we cannot yet see...." Then, it goes on to list what all these different people did by faith. Such as, " It was by faith that the people of Israel went right through the Red Sea as though they were on dry ground. But when the Egyptians followed, they were all drowned. It was by faith that the people of Israel marched around Jericho seven days, and the walls came crashing down. It was by faith that Rahab the prostitute did not die with all the others in her city who refused to obey God. For she had given a friendly welcome to the spies. Well, how much more do I need to say? It would take too long to recount the stories of the faith of Gideon, Barak, Samson, Jephthat, David, Samuel, and all the prophets. By faith these people overthrew kingdoms, ruled with justice, and received what God had promised them. They shut the mouths of lions, quenched the flames of fire, and escaped death by the edge of the sword. Their wekaness was turned to strength. They became strong in battle and put whole armies to flight. Women received their loved ones back again from death."

I love this chapter.
