When Paul was at Athens he was led to adapt his style of instruction to the character of his auditors, and he was thus obliged to occupy much of his time in discussing the principles of natural religion. He endeavoured to gain over the citizens by shewing them that their views of the Godhead could not stand the test of a vigorous and discriminating logic, and that Christianity alone rested on a sound philosophical foundation. But the exposition of a pure system of theism had comparatively little influence on the hearts and consciences of these system-builders. Considering the time and skill devoted to its culture, Athens had yielded perhaps less spiritual fruit than any field of labour on which he had yet operated. When he arrived in Corinth he resolved, therefore, to avoid, as much as possible, mere metaphysical argumentation, and he sought rather to stir up sinners to flee from the wrath to come by pressing home upon them earnestly the peculiar doctrines of revelation. In the first epistle, addressed subsequently to the Church now established in this place, he thus describes the spirit in which he conducted his apostolical ministrations. "And I, brethren," says he, "when I came to you, came not with excellency of speech or of wisdom, declaring unto you the testimony of God--for I determined not to know anything among you save _Jesus Christ and Him crucified_; and my speech and my preaching was, not with enticing words of man's wisdom, but in demonstration of the Spirit and of power--that your faith should not stand in the wisdom of men, but in the power of God." [108:1]
