When Whitefield was preaching before a very large number of the seamen of New York, he introduced the following bold apostrophe into his sermon: "Well, my boys, we have a cloudless sky, and are making fine headway over a smooth sea, before a light breeze, and we shall soon lose sight of land. But what means this sudden lowering of the heavens, and that dark cloud arising from beneath the western horizon? Hark! don't you hear the distant thunder? Don't you see those flashes of lightning? There is a storm gathering. Every man to his duty. How the waves rush and dash against the ship! The air is dark. The tempest rages. Our masts are gone! What next?" The unsuspecting tars, reminded of former perils on the deep, as if struck by the power of magic, arose, and with united voices exclaimed, "Take to the longboat, sir!" The reader may well imagine how this very natural answer would be used by the preacher. While at New York, Whitefield wrote, "God willing, in about seven months I hope to see New England on my return to Europe. An effectual door is there opened, and no wonder there are many adversaries. Shortly I expect to suffer for my dear Master." And after his return to Philadelphia, he showed his piety and meekness by writing to the Rev. Dr. Pemberton, of New York, "I have been much concerned since I saw you, lest I behaved not with that humility towards you which is due from a babe to a father in Christ; but you know, reverend sir, how difficult it is to meet with success, and not be puffed up with it; and therefore, if any such thing was discernible in my conduct, O pity me, and pray to the Lord to heal my pride. All I can say is, that I desire to learn of Jesus Christ to be meek and lowly in heart; but my corruptions are so strong, and my employ so dangerous, that I am sometimes afraid." One of the most important incidents of this journey to New York, was the meeting of Whitefield with Gilbert Tennent. Two powerful preachers could hardly resemble each other less; and the great strength of each lay in characteristics in which the other was deficient. In one point, especially, Whitefield felt and recorded his new friend's superiority. He heard Tennent preach. "Never before heard I such a searching sermon. He went to the bottom indeed, and did not 'daub with untempered mortar.' He convinced me, more and more, that we can preach the gospel of Christ no further than we have experienced the power of it in our hearts. I found what a babe and novice I was in the things of God." These men, as Tracy says, having once met, could not but be friends and allies for life; and the effects of their alliance could not fail to be felt by thousands.
