The first practice of God-centered preaching is exegetical. The second practice is homiletical. Once we identify the meaning and purpose of the text, and identify the vision of God and how that vision meets our need as fallen creatures, we must structure the sermon to reveal the need exposed in the passage, encountered in the people before us, and how it is met in God. This takes pastoral sensitivity and a commitment to accurately communicate Scripture to real people.
Since Scripture reveals God's saving acts, culminating in Christ's accomplishments at the cross, we are essentially applying the gospel to every need. Every sermon becomes an exposition of the gospel. However, we do not apply the gospel in a rote manner. The vision of God, and the human factor raised in the text, provide fresh avenues to communicate the gospel to a variety of human situations faced by the people before us.
