Flags were symbolic in the Old Testament in several ways. They were also called Banners, Standards or Ensigns. Flags identified armies marching into war and displayed God's protection over His people.(PSALMS 150:6)
Some people never used a Flag or Praise & Worship instrument at all, but I still believe that they were really touched and basked in the mighty presence of the Lord. Remember, we are to be "Sensitive" to the Holy Spirits leading and be Obedient to that. People can be touched by watching others. If it is the Lord, He can use anyone to Minister to others. I do believe that each person that attended Dance Boot camp 09 had a touch from the Lord, whether they came to previous ones or this is their first time like myself. I believe that people were blessed, by the Lord. The Lord showed up mightily. It was always based on whatever He wanted to do at the time; we let HIM reign and have HIS way. there are three different reasons we use the flag:
Praise and Worship
Intercessory Prayer
Spiritual Warfare
We "Flow" in different ways for each reason we are using them at that time. I do know the power and deepness that this takes others into. It enhances what one has, when doing any of the three above. I do believe that there are those that are specifically "Called" to do this in front of others. I believe that He "Births" this calling into His people. Just as we know we all have spiritual gifts that differ within the body of Christ, I believe that this is one of the callings that He can place on some-ones heart and "Birth" it in them and ask them to minister it.
