1 John 5:20 And we know that the Son of God is come, and hath given us an understanding, that we may know him that is true, and we are in him that is true, even in his Son Jesus Christ. This is the true God, and eternal life.
There is a tale told of that great English actor Macready. An eminent preacher once said to him:
"I wish you would explain to me something."
"Well, what is it? I don’t know that I can explain anything to a preacher."
"What is the reason for the difference between you and me? You are appearing before crowds night after night with fiction, and the crowds follow you wherever you go. I am preaching the essential and unchangeable truth, and I am not getting any crowd at all!"
