In this temperance work as in his preaching, and his attacks on evil of any sort John Chambers was as bold as a lion. He spent much time and travelled to many places in order to take part in temperance meetings and encourage the workers. In Neil Dow's reminiscences, page 416, is an account of a great temperance meeting in New York on February 19th, 1852, at which the Philadelphia pastor was present. Dr. Crowell tells of another held at Chester, Pa. Dr. A. A. Willetts and Dr. Theodore Cuyler were often with the "War Horse" in his campaigns. On one occasion when a barkeeper repeatedly sold liquor to one who was near and dear to the pastor and already a victim to physical decay and disease, induced by his drinking habits, Mr. Chambers went into the saloon, stated the exact case to the barkeeper and warned him not to sell any more liquor to the patient. Escaping from his nurse, the wretched man entered the saloon, again procured liquor and became decidedly worse. Finding what had been done, Mr. Chambers went to the barkeeper in fiery anger and said: "Didn't I warn you not to sell liquor to ----?" Then seizing him by his shoulders, he gave the publican a vigorous shaking, and again warned him, threatening a severe penalty. The barkeeper was so mightily impressed, that he is said to have sold no more to the patient. During all these early years, Mr. Chambers kept his young men busy in active evangelical work, especially in the holding of neighborhood prayer meetings on what were then the outskirts of the city. In 1875, Rev. J. J. Baker, pastor of a Baptist Church at Navesink, N. J., testified at the jubilee meeting to the intense activity of the young men of the church, with which he had united in 1829. Four whom he named, Summers, Burnham, Hunterson, and Town entered the ministry. He told of the zeal and activity of elders Hibbert and Arrison. "The young men of that time were interested in two prayer meetings, one held in the 'old frame,' as it was called--a barn down town, out of which effort grew 'The Cedar Street Presbyterian Church.' The other prayer meeting was held in 'The Girard School House,' out of which grew two churches, one Lutheran and one Baptist."
