TLDR: Accept Jesus, not a mark that allows you to buy and sell - Both are coming
What you are witnessing in this world is the rise of the antichrist system. There is going to come a time when you will be required to take a mark in order to buy or sell or participate in society. Do you see it coming? Can you feel it? I remember when I was a child and learning about the mark and the antichrist system, I couldn't understand how it would be possible. There were no personal computers. There were no satellites. The internet did not exist. Money was exchanged physically only. How would it be possible for one man to gain control of the whole world? And how could people allow it to happen when there was this book telling them exactly what would happen?
My, how things have changed. Knowledge has increased. People have largely relegated the Bible and God to fairy tales because of the constant lies they have been told. Do you see now all the lies that have been told and how they do it? It didn't start with Donald Trump's presidency. You have been manipulated and lied to your entire life.
The Bible tells us exactly how people will behave and what events will take place in the last days, and boy is it spot on.
You may have rejected all of the amazing Bible prophecies that have been fulfilled in the past - but what will you do when you are presented with their fulfillment in your life? If you are presented with a mark to be put your forehead or right hand that gives you permission to buy and sell - remember that it was foretold, and do not take that mark because it signifies your worship of the beast, and you will perish.
Great violence is coming. It is coming in the form of natural disasters, diseases, famines, and war.
Jesus Christ is the only way to eternal life, and He is the only way to escape what is coming on the Earth.
Accept the sacrifice that Christ made. With your mouth, declare that He is the Lord and Saviour. Repent of your sins, and He will forgive you, and you will be saved.
Time is short.
It's not a physical mark. Gods people are marked too. The hand is your actions and forehead your thoughts. It's basically you taking part in the system to save yourself in this life. Example being the system forcing you to do something against Gods will.
