A victory made possible by Divine warfare. There are two possibilities as far as warfare is concerned, and they are: Divine warfare, or spiritual warfare. It's spiritual warfare when we fight by ourselves with the full armor of God as specified in Ephesians 6: 12-18, but Divine warfare when God Himself fights without our interference or participation.
We engage in spiritual warfare through prayers, God engages in Divine warfare by our praise. In this Scripture, David taught us how to trigger God's saving power from rampaging and terrible enemies. He said it happens when we call upon the LORD with full understanding that He is worthy to be praised.
This involves calling upon God while recognizing His "worth", His "value", His "acts" and His "power". It involves calling upon God by recognizing His track-record of doing great and wonderful things. According to him, when we call upon God this way, automatic salvation from covenant enemies happens.
The praise that invites God to act is a praise done with understanding. A praise done while thinking about His power, His miracles, and His acts. You must have documented some of His works mentally for you to praise this way.
Praise is ineffective if we do not render it with understanding. Power is released through praise when we praise God by thinking about and counting out His acts and His works in our lives. Don't make praise a singing and dancing affair.
No matter how you dance and sing, the actual power only comes when you subject your thoughts to the same praise. In other words, the power of praise becomes manifest when the mouth, the body, and the heart participate. Don't be distracted while praising, distractions are satanic arrows channeled towards weakening our praise.
Then arise and praise Him while meditating on these and He will arise and fight in Jesus mighty name!
