This is exactly one of the examples of lay witnessing we've pointed to in the thread, Lynnie- as well as the Samaritan woman at the well, who witnessed to her neighbors of what Christ had done for her and invited them to come and hear for themselves. To bear witness of Christ is to testify to others what we have seen and known of him. We commend him to others, waxing eloquent as best we can.38 Now the man from whom the demons had departed begged Him that he might be with Him. But Jesus sent him away, saying, 39 “Return to your own house, and tell what great things God has done for you.” And he went his way and proclaimed throughout the whole city what great things Jesus had done for him.
I would have to say that maybe God might have somebody not ordained wax eloquent in the public square.
