Worship empowers serving; serving expresses worship. Godliness requires a disciplined balance between the two. Those who can maintain service without regular personal and corporate worship are serving in the flesh. It doesn’t matter how long they’ve been serving that way or how well others think they serve, they are not striving according to God’s power, as Paul did, but their own… At the same time, one measure of the authenticity of worship (again, both personal and corporate) is whether it results in a desire to serve… Therefore, we must maintain that to be Godly, we should discipline ourselves for both worship and service. To engage in one without the other is, in reality, to experience neither.
