An artist, seeking to depict on canvas the meaning of evangelism, painted a storm at sea. Black clouds filled the sky. Illuminated by a flash of lightning, a little boat could be seen disintegrating under the pounding of the ocean. People were struggling in the swirling waters, their anguished faces crying out for help. The only glimmer of hope appeared in the foreground of the painting, where a large rock protruded out of the water. There, clutching desperately with both hands, was one lone seaman.

It was a moving scene. Looking at the painting, one could see in the tempest a symbol of humankind's hopeless condition. And, true to the Gospel, the only hope of salvation was "the Rock of Ages", a shelter in the time of storm.

But as the artist reflected upon his work, he realized that the painting did not accurately portray his subject. So he discarded the canvas, and painted another. It was very similar to the first: the black clouds, the flashing lightning, the angry waters, the little boat crushed by the pounding waves, and the crew vainly struggling in the water. In the foreground the seaman was clutching the large rock for salvation. But the artist made one change: the survivor was holding on with only one hand, and with the other hand he was reaching down to pull up a drowning friend.

That is the New Testament picture of witnessing - that hand reaching down to rescue the perishing. Until that hand is extended, there is no Gospel - and there is no hope for the world.
