The Reality of Buying and Selling and the Mark of the Beast
Your human efforts will not get you through. You must trust that Jesus will sustain you.
People are buying property in rural areas outside of cities, thinking it will save them. Unfortunately, the government keeps very good property records. You will owe property tax. So not only will you need to "buy and sell" to pay that tax, the government can track you.
Are you storing food? Not a bad idea to store a little food for an emergency event. However, it will not sustain you in the last days. That is putting your trust in your efforts. Do you think your neighbors will not find out? If it is the time of great trouble, they will rob and kill you.
Same thing holds of you are planting a garden in hope of eating off the land. The world will be a disastrous place, hardly fit for growing anything. Can you keep the hungry mobs away?
Many are storing gold, thinking it can be used as currency to get around buying and selling. Your gold will be worthless. Who would want it? Food, water, and shelter are going to be scarce for everyone. You cannot eat gold. Jesus warned about putting your faith in earthly riches.
A lot of people are misinformed about the great tribulation and buying and selling. it means exactly that. You will not be buying and selling unless you have the mark of the beast.
That means your cellphone is gone. You cannot even charge it, as that takes electricity. You will not own property, a house, or pay any bill.
The Seventh-day Adventist Church will not be around very long. The organization will cease to exist. The buildings, hospitals, colleges, churches, academies, and more, will not be sustained without buying and selling. They must be abandoned by the church, as no bills are able to be paid.
Think of what personally is involved with buying and selling. Gasoline, food, water, electricity, insurance, cellphones, internet, car registration, property taxes. None of these can be paid for by someone who does not have the mark.
Don't be foolish about buying and selling, thinking you can outsmart the evil powers. You should put your trust 100% in God.
