1 Thessalonians 5:21
Prove all things; hold fast that which is good.
It is related that Bishop Kavanagh was one day walking when he met a prominent physician, who offered him a seat in his carriage. The physician was an infidel, and the conversation turned upon religion. "I am surprised," said the doctor, "that such an intelligent man as you should believe such an old fable as that." The bishop said, "Doctor, suppose years ago some one had recommended to you a prescription for pulmonary consumption, and you had procured the prescription and taken it according to order, and had been cured of that terrible disease, what would you say of the man who would not try your prescription?" "I should say he was a fool." "Twenty-five years ago," said Kavanagh, "I tried the power of God's grace. It made a different man of me. All these years I have preached salvation, and wherever accepted have never known it to fail."
