I have learned that the Holy Spirit moves in many ways in a service.
#1 He's always there. We never have to "call him down" to join us.
#2 Even if people aren't jumping and freaking out doesnt mean they aren't worshiping.
#3 The Holy Spirit moves on people through conviction and healing that we may not see manifest on the outside.
I have learned to depend on the Holy Spirit to move in whatever way He wants, and how ever that looks is fine with me, as long as i have spent time in prep and prayer and provide the oppurtunity, there is nothing more that "I" can do, only the Holy Spirit.
One thing that I have recently added is using more scripture during worship. The word of the Lord never returns void and is sharper than a double edged sword and its working, verses, using "my" words to pump people up. Hope this helps
