Hello beloved brother!
- Has the COVID-19 vaccine anything to do with Christ?
- Is it a sin to get that vaccine?
- Has it really to do with the end of the ages?
- What could a Christian do in the vaccination process (accept or deny)?
- Who is the evil man Paul talks about? (it won't be so until the evil one is revealed)
"For thus the LORD spoke to me with mighty power and instructed me not to walk in the way of this people, saying, 'You are not to say, 'It is a conspiracy!' In regard to all that this people call a conspiracy, and you are not to fear what they fear or be in dread of it. It is the LORD of hosts whom you should regard as holy. And He shall be your fear, and He shall be your dread'" (Isaiah 8:11-13).
You will always find people finding things to stir up feelings of panic. Ever since Jesus said that he would return, people have been seeing "signs" of his return in every event in the world despite the fact that Jesus said there would not be any signs.
"But of that day and hour no one knows, not even the angels of heaven, nor the Son, but the Father alone" (Matthew 24:36).
"For as in those days before the flood they were eating and drinking, marrying and giving in marriage, until the day that Noah entered the ark, and they did not understand until the flood came and took them all away; so will the coming of the Son of Man be" (Matthew 38-39).
"For this reason you also must be ready; for the Son of Man is coming at an hour when you do not think He will" (Matthew 24:44).
"The master of that slave will come on a day when he does not expect him and at an hour which he does not know" (Matthew 24:50).
"Be on the alert then, for you do not know the day nor the hour" (Matthew 25:13).
Revelation mostly deals with the fall of the Roman Empire and the mark of the beast had to do with providing evidence that a person was loyal to the emperor and worshiped at his altar. See 666 and the Mark of the Beast. Now, it is true that history repeats itself, so it is not surprising that we hear of places, like China, requiring Christians to denounce their religion in order to receive government services. These are not signs of Jesus' second coming. They are the product of men forgetting the lessons of history.
In regards to the man of sin, see The Man of Sin.
