Question: In Daniel 12:4, the Bible says that knowledge shall be greatly increased. Did God ever predict that we would have television?
Answer: Yes, our omniscient God did predict the whole world would see certain events that He prophesied would happen. He did not say by what means the whole world would see it, only that it would.
For example: three and a half years after the Rapture, in the middle of the 7-year Tribulation, the two witnesses are put to death by the Antichrist. Their bodies are not buried, but put on display for 3 and a half days and the whole world will see it. God’s word tells us in Revelation 11:9
"And they of the people and kindreds and tongues and nations shall SEE their dead bodies three days and an half, and shall not suffer their dead bodies to be put in graves."
Before satellite TV this would have been impossible; but, now the whole world will see this event just as God had predicted almost 2,000 years ago.
God has also predicted in 1 John 5:13 that
"These things have I written unto you that BELIEVE on the name of the Son of God (Jesus Christ); that ye may know that ye have eternal life..."
