Praise is truly the weapon for today. When we praise God, we are raised to His presence. He is worthy of all praises. The book of psalms is full of praises. When kings and priests and the congregations (the people of God) praised God as recorded in the history of Israel, their enemies dreaded, were confused, self=destructed, and whatever who were not destroyed fled..
This is the power of God’s presence. His glory. His holiness. His God-ship. All these come upon us as we praise. The power of praise can be experienced even by worshiping together in one accord, joined to the Lord, one Spirit with Him! I have found some resources on this subject and I personally have found them useful.

Praise actually ministers unto God. This series will explain how praise affects the devil, God, and us. Praise is God’s antidote to fear and the pessimism of the world.”

The Apostle Paul gave us a great example of this. He had a vision from God that he was supposed to go minister to the people in Macedonia.
And a vision appeared to Paul in the night; There stood a man of Macedonia, and prayed him, saying, Come over into Macedonia, and help us.  And after he had seen the vision, immediately we endeavoured to go into Macedonia, assuredly gathering that the Lord had called us for to preach the gospel unto them.
Even though Paul and his companion Silas had a divine mandate from God to go and minister there, everything didn’t go perfectly. Within just a few days, they were beaten and thrown in the worst part of the prison with their feet and hands in stocks (Acts 16:16-24).
But look at Paul and Silas’s response to this:
And at midnight Paul and Silas prayed, and sang praises unto God: and the prisoners heard them.
This is awesome!…” Read more from this link: http://www.awmi.net/extra/article/pauls_secrets
