I think what I've come to realize in the past couple of years is that times of worship where no one knows what it is, it's because we're all together. It's just that simple. I mean, you could bring Christians from different denominations together and not say anything, and it would be the most powerful expression of worship - because it's a fulfillment of Jesus' prayer in John 17. God's not a liar. The things that He says, His word won't return null adn void. So when Jesus prays before Calvary that we would be one, whenever that happens, we are agreeing with the Lord, and whenever we agree with the Lord, there's a goodness about it, we're in right relationship. And so I think whenever the church worships together, it's going to be palpable ... it's not about the gifts and the talents, it's about the fact that we're all together. That's the gift. That's the anointing. The anointing isn't in a person, it's in the body of Christ, and when the body of Christ is reconciled by worshipping together, that's where the anointing is.
