Praising God is more than just telling Him what an awesome God He is. Even though it is that, there's MORE. There's always more!!
Several scriptural stories illustrate this point. The walls of Jericho came down through the praising and blowing of trumpets of the Israelites. Paul and Silas were praising in the jail when there was an earthquake and the prison cells were opened. We have talked about Jehoshaphat before. He went into battle with his singers out front. Wow!
Watch this video from Max Lacado. He explains it very well.
