Is this a dance?
Yes and No. Yes, because tradition flags in worship are like performances and you need to follow a certain routine to be in-sync with the other performers. There is certainly a place for this form of expression in major churches or large celebration events.
There is another expression that depends on the leading of the Holy Spirit. The Holy Spirit can take you to levels and dance sequences you never believe possible. Just like speaking in tongues, you never know what words or language comes next. Knowing a certain basic movements helps but not a prerequisite. The excitement is to discover the new creative moves each time He leads you. This you will never grow tired or feels like a routine.
Creative freedom is one of the most satisfying aspect of worshiping with flags. When you allow the Holy Spirit to lead you, your creativity becomes accelerated. Invite him be your dance partner & he is forever forgiving. No matter what new step you may choose to take, he is able to keep in lock-step with you all the time. Worship Flags.
