Ephesians 3:10 ..."through the Church the multifaceted wisdom of God should now be disclosed to the rulers and the authorities in the heavenly realms."

Different strokes for different folks...

My opinion... Worship Pastor... yes!, Worship Leader... not necessarily. (I love Tiffany's reference to Ross Parsley's Article)

I don't know your exact title @ Northpoint Los, but I would assume that you fill the "Worship Pastor" Roll and contract Worship Leaders to lead. In a Church that size it's probably a good idea for you to get stage time as much as possible whether you're leading or not. Maybe even weekly if possible.

Without leadership the people will fail in their worship.

I've been a part of mega-churches, church plants and medium sized churches with various systems for worship. Some of my most memorable worship experiences are from a mega-church that didn't have a Worship Pastor. The music culture there was amazing! The main reason??? They had a non-musical Pastor that ministered to and coordinated with the worship culture.

Question #1 Yes! (Worship Pastor)
Question #2 No! (Worship Leader)
