When you use your smart phone you can literally touch the whole world. You can talk to anyone in any country, send and receive images and movies, you can video chat with anyone, you can buy almost anything from anywhere in the world. This was not so even a few years ago. The knowledge to make such communication was non-existent. A hundred years ago you placed a call through an operator and waited while she plugged in a wire to the next operator down the line and so on and so on until the telephone rang a required number of rings on the party line and your friend answered the call. That works until you reached the oceans. To go inter-continental you had to use Snell mail which could take days, weeks or months to get through. Other areas of our daily life were impossible a short time ago but now are normal. Autos, Aircraft, Missiles, Smart weapons, Radoi, TV, Electronic banking, Internet and many others are part of our daily lives only recently. and much more.
Daniel was told of a time when Knowledge would explode.
Daniel 12:4 "But thou, O Daniel, shut up the words, and seal the book, even to the time of the end: many shall run to and fro, and knowledge shall be increased."
This is just another sign that we are fast approaching the end of days and Jesus will soon return.
