Essential Elements of Success in Preaching. II. Sincerity.

The devout Richard Baxter once said: “The ministerial work must be managed purely for God and the salvation of the people, and not for any private ends of our own. This is our sincerity in it. A wrong end makes all the work bad from us, however good in itself.” In order to success, it is necessary not only to display a fearless courage, but also a spirit of unmistakable ingenuousness and sincerity. As the mountain tarn reflects the clear, chaste light of the stars as they kindle in the heavens, so the preacher reflects in his outward conduct the pure and lofty motives by which he is animated and sustained. We observe, in connection with the preaching of the Gospel at Thessalonica, sincerity in motive, in speech, in aim.

I. Sincerity in motive.—“For our exhortation was not of deceit, nor of uncleanness, nor in guile” (ver. 3). The apostle disclaims the harbouring of evil intentions in relation to God, himself, and others.

1. In relation to God.—“Not of deceit”—not in error. Having received the truth from God and about God, he transmits it in all its integrity, without error or imposture.

2. In relation to himself.—“Nor of uncleanness.” Pure in his own affection and purpose, he preached a Gospel that was pure in itself, in its tendency, and in its experienced results.

3. In relation to others.—“Not in guile.” He sought not to propagate the Gospel by any fraudulent wiles or false representations. He descended not to hypocrisy to catch men. “Hypocrites,” says St. Bernard, “desire to seem not to be good; not to seem, but to be evil: they care not to follow or practise virtue, but to colour vice by putting upon it the painted complexion of virtue.” The life of the man whose motives are thus sincere will be transparent as the light. A certain king of Castile, who had been only too familiar with the duplicity of mankind, once somewhat arrogantly said, “When God made man He left one capital defect: He ought to have set a window in his breast.” The sincere man opens a window in his own breast by the whole tenor of His words and actions, so that his innermost thoughts are apparent.

II. Sincerity in speech.—1. The preacher speaks under a solemn sense of responsibility. “But as we were allowed of God to be put in trust with the gospel, even so we speak” (ver. 4). To their charge, as men tested and approved of God, was committed the precious treasure of the Gospel; and keenly conscious of the unutterable riches with which they were entrusted, they were deeply solicitous to distribute the same in all faithfulness and sincerity. Every gift we receive from Heaven has its corresponding responsibility.

2. The preacher seeks chiefly the Divine approval.—“Not as pleasing men, but God, which trieth our hearts” (ver. 4). There is much in the Gospel distasteful to the natural man—its humiliating exposure of our depravity and helplessness, its holiness, its mysteries, the unbending severity of its law, and the absolute character of its claims. The temptation is sometimes great to temper and modify the truth to carnal prejudice, and sacrifice faithfulness to popularity. But the apostles risked everything so that they secured the Divine approval. “As of sincerity, as of God, in the sight of God speak we in Christ” (2 Cor. ii. 17).
