There are two camps of people in the church those that are still praising Him at the Red Sea and those that are praising Him in the promise land. People that praise the Lord at the Red Sea are those who have yet to possess the evidence of the total promise. Those that praised the Lord in the Promised Land were those who were led by the spirit to praise about the problem confronting them--- that had purposed praise. Their praise brought down the walls---impregnable walls---impossible walls! But in order for them to have a praise of that magnitude, they had to obey the Lord and shout when He said shout.
