What is worship dance?
Webster’s Dictionary defines dancing as "to move the body, especially the feet, in rhythm, ordinarily to music." The Hebrew word used in the Old Testament carried with it the idea of whirling and turning. Greek words used in the New Testament have to do with lifting up the feet or leaping with regularity of motion. Also, Hebrew words that have meanings related to physical movement were translated into English as "rejoice".
Worship dance is simply dance in the form that God created it to be. It is movement that expresses, communicates, and prophesies love and praise for Jesus our Savior.
Basileia is committed to dance that is from and for God. We dance in praise and worship of our Maker, and call upon His manifest presence always.
