The great opera singer Pavarotti held a concert in the United States late 1992. As he was singing, his voice cracked. When this happened people stood up and booed. One reporter said he felt that if the people would have had tomatoes, they would have thrown them. People felt the right to boo, especially since they had paid $1,200 per seat!
I guess that's the way it is with church people in some of the big churches these days. They pay their pastors so much that he’d better not make any mistakes, especially in a sermon. Better not preach any duds! Missionaries on furlough, however, do not have to worry as they don't get much salary at all.
We as missionaries may get beaten, and rocks thrown at us but at least we don't need to worry about thrown tomatoes on furlough!
