The story is told of a Christian college where the preacher students took turns speaking in chapel every Thursday. There was one freshman preacher student, though, who had avoided the dreaded task of preaching at chapel long enough that it came to the attention of the Chapel Master. The following conversation ensued:
"I'm scheduling you to preach at chapel next Thursday."
"Oh, please. I'll do anything. I'll write a paper, do extra homework assignments, even clean the toilets. Just please don't make me speak in public yet."
"You are not getting out of this, and there will be no excuses."
Thursday rolled around and, with desperately quaking knees, the young student stood up to preach, and asked, "Do you know what I'm going to say?" Everyone shook their heads no. "Neither do I. Go in peace."
The Chapel Master was really angry. "That is not acceptable. You are right back on the schedule for next Thursday, and this time you will preach, and it will be an example of diligent preparation, and there will be no excuses."
Thursday rolled around and, with yet more quaking, the young man stood up to preach and asked, "Do you know what I'm going to say?" Everybody nodded their heads yes. "Good. Go in peace."
The Chapel Master was absolutely outraged. "There will be no more of these shenanigans. You will preach the word of God next Thursday. You will not fail, or you will be removed from school immediately."
Thursday rolled around and, barely able to stand, the student got up to preach and asked, "Do you know what I'm going to say?"
Some shook their heads no; others nodded their heads yes.
"Good. Those who know, please tell those who don't. Go in peace."
Not a bad summary of the Great Commission and our task of evangelism. Those who know ought to tell those who don't.
And Jesus came and spoke to them, saying, 'All authority has been given to Me in heaven and on earth. Go therefore and make disciples of all the nations, baptizing them in the name of the Father and of the Son and of the Holy Spirit, teaching them to observe all things that I have commanded you; and lo, I am with you always, even to the end of the age' || Matthew 28:18-20
