Is revelations in the Bible happening yet?

Everything in Revelation past chapter 3 is all yet future (in other words, hasn't happened yet).  There is a very brief moment at the beginning of chapter 12 that is a quick look back at past events, but other than that, everything past chapter 3 is all yet future.  So it hasn't happened yet, but we do see the stepping stones to getting there.  For example, the technology and mentality both exist for the coming mark of the beast.  We also see the world coming together in world government which will be led by the antichrist in the future.  We also see religions trying to come together, and once most of them do, they will worship the future antichrist.  And Israel is a nation again, which is required for Revelation.  So it's happening in terms of stepping stones, all around us. The Bible is the Word of God.  The Bible is true.  The Lord Jesus Christ is God, and He loves you.  Believing in the Lord Jesus Christ means being forgiven all sins past and future, and means going to heaven and not hell.  Death leads to immediate heaven or hell, and it is too late to be saved, after death.  All believers still sin.  See 1 John 1:8.  To be in heaven and not hell, believe in the Lord Jesus Christ, who is God and who died on the cross and shed His blood to pay for all of our sins in full, and who was buried, and who resurrected from the dead.  The only way to avoid hell is by believing in the Lord Jesus Christ, without adding any of your own works.  See Romans 4:5, 1 Corinthians 15:3-4, and John 3:16.

It is beginning to happen but there is quite a lot happening so this won't be ended overnight.  We are told to watch for the signs.

No.  And it's "Revelation."

Yes, the prophecies told of in Revelation is being fulfilled.
One must study the Bible to understand what is going on in the World today.
Most do not understand The Book of Revelation and that will lead those to be deceived.

The first four signs of Revelation have already happened the most notable the most traceable signs are the burning in the great city called Babylon which causes all the nations of the world to cry and moan because nobody has any money anymore we're referring to 911 here.

The next traceable sign is the coronavirus the fourth sign the ball upon what is translated to be the Sun.

But the Greek words used are Coronas feverum.

It literally means Corona fever

You mean the Book of Revelation don't you?

Revelation depicts Jesus' judgment and destruction of ancient Rome. It was all fulfilled by 1400 AD. Most of its content transpired during the dark/middle ages. 

Yes! Trump is the Antichrist!

Revelation is a book of prophecy for the future. Genesis tells how the world began, along with how sin came about; Revelation is the result of God's original purpose for mankind unfolding and the benefits that are waiting for obedient mankind.

Yes, we are in the events of the fifth or sixth seal.  The four horsemen are history, and Rev. 14:6 has been fulfilled -- the everlasting gospel of Christ being restored to the Earth in the last days by angelic ministry.

most of it happened before 100AD
