What are you going through right now?  Can you trust God to get you through it?  Noah built an ark as God told him to... for 100 years.  Then when God told him to load it, he did, and then he told him to get on it with his family... that the rain was coming.  Noah obey.  Noah's faith in action.

Check out this life size Ark, and Ken Ham talking about it.
