I think misguided priorities, also. Some took it so they could continue to earn an income, to ensure their families could continue to afford food and housing. If it was a harmless vaxx, this may have been a reasonable choice. For me, I believe it crossed the line between dividing what is God's, and what is Caesar's - give to God what is God's (i.e. the man) and to Caesar what is Caesar's (the taxes/coins/money).
We should break that down because this will become the major issue during the tribulation (which is ever so close to starting). You can see many people who were damaged from the vaccine saying it wasn't worth it, keeping their job wasn't worth it. That is a pre tribulation warning to everyone, it is not worth it to exchange eternal salvation for a bowl of red beans by taking the mark of the beast.
My wife and I were in the same position, my son was just about to start college, we were not ready to retire by any stretch, my job as a teacher still needed another 12 years before I would get my "full" pension. I am old enough to claim Social Security but all the metrics say if you are healthy you should put that off for a few more years at least. We were happy with our jobs, happy with our church, and selling the house was a very difficult job for us (don't want to go into the details but a much more difficult process than it would be for most people).
And yet within 24 hours of DeBlasio mandating the vaccine I began the process of retiring and my wife also determined not to get the vaccine even if it meant she had to give up her job which she did. Why? The answer is simple, as soon as the pandemic hit I dove into the word, spending an extra hour or two a day. I immediately saw that Joel prophesied concerning this pandemic and that this pandemic was a sign that the day of the Lord is at hand. Because I dove into the prophecies and into the word I had the full assurance that the tribulation was about to start. As a result I wasn't worried about having money saved up for the next thirty years. It also became clear to me that these liars were pushing some hidden agenda and whatever it was I didn't want any part of it.
Watchmen Nee once shared an example of trying to navigate a rushing mountain stream filled with rocks. The solution is not to see the rocks because in the end you will end up on them, your boat crushed and you drowned. The solution is to raise the water level in the stream so that you can go over the rocks. The only way people will have the life supply to reject the mark of the beast is if the level of grace is at full.
