It is very tempting to conceive of a worship leader as the spiritual engine that drives the worship train, or the highly-charged sideline coach who needs to keep her team fired up.
This puts all the focus on our agency, a vision that doesn’t square with the New Testament. In the New Testament, our agency as worshipers and leaders is intimately linked with what Jesus is doing as we worship and with what the Holy Spirit is doing as we worship. Remember these comforting words: “the Spirit helps us in our weakness” (Rom. 8:26).
In the past few years there has been a lot of attention drawn to the emotional engagement of up-front worship leaders. We hear and read things like “you cannot lead others in worship unless you are a worshiper,” or “how can you expect to lead people into the throne room of God if you haven’t been there yourself?”
I can see the appeal of these statements—the way they prophetically address those of us who simply go through the motions or those of us who stoically dismiss emotional engagement as unimportant. But they can also discourage and demoralize us in their exaggerated incompleteness. Your congregation’s worship is not ultimately mediated by your level of or capacity for emotional engagement but by the perfect mediating work of Jesus, effected through the Holy Spirit. Praise God! This can free you—and all of us—to engage emotionally, but without a sense of burden that it all depends on us.
