The reasons I think the second coming of Christ is

Jesus said that " Just as it was in the days of Noah, so will it be in the days of the Son of Man."

Think about how it was in the days of Noah, everyone knows that there were giants but other things are like today. In Noah's day people lived hundreds of years. Think about the life extension tech we are seeing today like the fact that they have unlocked the mystery of aging. Revelation talks about man seeking death and not finding it. revelation also talks about the mark which we will have to take to buy and sell, we in the United States already have to have a social security number to work. But for most, we didn't volunteer for that number but what if they came up with a chip that not only replaced money but changed your DNA so you could live 4 or 5 hundred years disease free. Would you volunteer for that?

Genesis talks about the fallen angels corrupting everything from women to fishes. Aren't we doing the same with the DNA experiments like cloning and the spider goat that is milked for spider silk, combining human and mouse DNA to grow a human ear on a mouses back.
Babies that can be born with the genes of three people that is supposed to prevent certain birth defects.

Wars and rumors of wars, isn't most of the world right now at war on some level.

Men will travel to and fro at great speeds. Have you heard about the new Hyperloop train that Paypal founder is planning that will take people from San Fransisco to LA in 30 minutes which is faster than an airplane which takes one and a half hours.

Just about everything we see today fits into the prophecies if you look.

I am not trying to convert anyone or tell anyone what to think or believe but even if you don't believe you have to admit that it is very interesting that a book written so long ago could describe the present day so well.

God bless
