Another excerpt from my EMA address:
The question I most want to ask any Christian, but especially any group of Christian leaders is "how would you describe the state of your worship life at the moment?" Do you currently have the space, capacity and leisure to enjoy God?
If not, something will have to go. The reason I say this is that biblical leadership and preaching are by-products of joy in God. They don't work properly unless they spring from this source. You can't say "I honour God in my preaching" if you heart is not bursting for him in your affections and adoration. You really can't.
The tasks of leadership and preaching centre around working with people for their progress in the Lord and their joy in the Lord (Phil 1, 2 Cor 4). And the strength to carry out the task, that ability to labour and struggle with God's energy powerfully working in us, comes from the joy of the Lord. How easily we forget that it is the joy of the Lord that is our strength and start to look for strength from other sources.
Therefore I conclude that the leadership task emerges out of joy in God, is empowered by Spirit-fuelled joy in God and is done in order that others have joy in God. Leadership and preaching are shot all the way through with dependence on joy in God. No joy, no good preaching and leading.
Worship (having adoring affections for God in every area of life) is the giving of expression to that joy. Worship reflects our joy back to God in exultation and to everyone around us in discipling them and evangelising. Discipleship and evangelism, just like biblical preaching are by-products of Holy Spirit-produced joy in God.
