"Firstly, we need to connect our preaching purpose to that of the Holy Spirit’s purpose. His aim is to glorify Jesus Christ through the means of the Scriptures—the Christocentric Scriptures. Therefore, I must be resolutely wedded to His intention in the sacred text: explaining the text in its context, applying the text as was originally designed, and displaying its inner-canonical connections which will lead me to Jesus Christ.
Secondly, we need to pray for that which only the Spirit can supply: potency to transform the human heart.
Thirdly, we need to be willing to suffer. Why? Because the apostolic pattern seems to indicate that God’s power is perfected in weakness. Are we willing to be weak so there are no competitors for glory when God does what only He can do?
Beyond this, of course, we must remember that Spirit is sovereign. 'The wind blows where it wishes.' Anything that smacks of a formula is sure to quench the Spirit rather than arouse His empowerment. This is the occupational hazard of the Christian ministry."
