One of my favorite stories from the Old Testament, David Vs. Goliath. Basically, David was the underdog in the fight and Goliath was used to being the champion. Even though Goliath was much stronger, David put is faith in the Lord and boldly defeated his enemy with a single stone.
A really great Bible resource online, Bible Gateway, has the full story here.
Thank you for stopping by and hope you have a wonderful Christmas this season. :)
