Well when the Bible says "the Love of most will grow cold" it is referring to the lack of love and the increase in violence in the last days.
The world is a thousand times better off than it was 2,000 years ago, brother.
Wholesale slaughter was not uncommon then. Murder was a recreational PASS-TIME in Rome.
The most civilized nation in the world in that day fed people to lions for entertainment.
Immorality was a MILLION times more rampant then. The Romans, I am told, did not even have a WORD for "homosexual" because it was not thought of as a distinct sexual practice from heterosexuality. It was EXTREMELY common for Roman men to have "boy lovers" and the nation did not frown upon this.
The most civilized nation in the world had massive sex temples built for the pagan gods serviced by a thousand prostitutes, male and female, where it was very commonplace to have massive orgies nightly.
If Matthew 24 requires the world to become more immoral before Jesus can return then we've got a while.
These are things many dispensationalists do not know.
