If we follow Deedat's logic, a fire truck cannot be a fire truck unless it says "fire truck" on its side. It can contain all the fire-fighting men and equipment such a vehicle may require and go from one fire to the next doing its job saving lives and property, but to Deedat's adherents, it will never be one unless it has the words "fire truck" on its side. Hence the need for this important warning:
That is, for as long as you insist on following Deedat's bad logic.
The moral of the story is: do not unthinkingly accept everything your showmen, imams or apologists tell you. Instead, think each claim through for soundness, rationality and good old common sense.
Soon enough, you will find yourselves reading the Bible and giving your lives to Jesus Christ as your Lord and Savior.
