Preachers need to understand that they perform a theological action that demands care and earnestness. They handle the word of God and bring the most important message of all to people’s ears. Their carefulness also rests on confidence because the power of the message does not reside ultimately in them as messengers but in the God who speaks through the message. Nothing kills churches faster than preachers who do not understand both elements of the task. Preachers need to understand God’s grace, not simply so that they can preach its content but also so that they can preach, period.
