It is desperately essential in this hour that preachers recover a soaring vision of the supremacy of God. Life-changing, history-altering preaching will come only when pastors reclaim a high view of God's blazing holiness and are overshadowed by His absolute sovereignty. Towering thoughts of God's transcendent glory must captivate preachers' souls.
Expository preaching consists in the explanation and application of a passage of Scripture. Without explanation it is not expository; without application it is not preaching.
May I beg you carefully to judge every preacher, not by his gifts, not by his elocutionary powers, not by his status in society, not by the respectability of his congregation, not by the prettiness of his church, but by this—does he preach the word of truth, the gospel of your salvation?
Without the gospel everything is useless and vain; without the gospel we are not Christians; without the gospel all riches is poverty, all wisdom folly before God; strength is weakness, and all the justice of man is under the condemnation of God. But by the knowledge of the gospel we are made children of God, brothers of Jesus Christ, fellow townsmen with the saints, citizens of the Kingdom of Heaven, heirs of God with Jesus Christ, by whom the poor are made rich, the weak strong, the fools wise, the sinner justified, the desolate comforted, the doubting sure, and slaves free. It is the power of God for the salvation of all those who believe.John Calvin's preface to Pierre Robert French translation of the New Testament (1534)
More and more am I jealous lest any views upon prophecy, church government, politics, or even systematic theology, should withdraw one of us from glorying in the cross of Christ. Salvation is a theme for which I would fain enlist every holy tongue. I am greedy after witnesses for the glorious gospel of the blessed God. O that Christ crucified were the universal burden of men of God.Lectures to My Students (p. 79). Zondervan
