I agree with you that the mark of the beast will be also technological. It looks like the merging of man and machine for the complete enslavement of the world. No one will be able to buy or sell without the mark, which will be in the right hand or forehead. So everyone will be tracked and must be in compliance to the beast system, or they can no longer buy anything, even food. Whoever takes the mark will lose all their freedom.

The COVID shots were the precursor. Already we saw people being denied service and entry into businesses if they did not have the shots. So they could not buy without the COVID shots. And other people lost their jobs because they did not take the shots, so they could no longer sell their goods and services. And technology is used to prove that the person received the shots, like the pass codes on a cell phone. And everyone must have a number for their name to have a cell phone. People will be tracked by this number or by the mark of the beast.

The injections change the genetic code of the human, so they are no longer made in the image of God, but are now becoming a beast, having corrupted themselves. Jesus came to save man, not to save beasts. Those that worship the beast and take his mark are damned. There is a spiritual aspect to this. Those that worship the beast have rejected God and the salvation he offers them through the sacrifice of Jesus on the cross. God is no longer sitting on the throne of their heart as their God, but the abomination of desolation sits there showing himself to be their god. People will worship the image of the beast.

If someone took the injection in ignorance, they can repent and pray to God for forgiveness, and he might heal them.

Those that take no injections have not been corrupted. The mark of the beast, however, is required to buy and sell, so even those that refused the COVID shots will be tempted to take the mark, because their faith in Jesus is weak or non-existent, and they think they have no hope without the mark to even have food to eat. Hunger will drive many to abandon their divine nature and become like wild animals. Those that stay faithful to Jesus until the end will receive blessings beyond your wildest expectations. We can't even describe with words the riches he has stored up for those who love him.
