You’ve said many times, and I believe you, that people saved during the Tribulation will be responsible for keeping their faith intact during the Tribulation. What exactly does that mean? I am saved but still sin, even though I don’t want to. Some of my sins include anger and sometimes cursing in that anger, but I always, ALWAYS ask God to forgive me because I am truly sorry afterward. If a Trib survivor has anger with maybe cursing included, will he have lost his Faith? Is his faith the same as my Faith? Do you mean that he can sin no more, ever? Wouldn’t that be impossible?
The only passage that describes the requirements of Tribulation believers is that they obey God’s commandments and remain faithful to Jesus (Rev. 14:12). It means they will have to keep the commandments as best as they can, trusting the blood of Jesus to cover them when they fall short. Old Testament standards were essentially the same, except they didn’t know the name of their Savior.
Except for taking the mark of the Beast, the Bible doesn’t identify any red lines beyond which salvation would be revoked, but based on what it does say more weight will be given to maintaining their faith than anything else. The Parable of the 10 virgins (Matt. 25:1-13) seems to bear this out.
It’s hard to compare our situation with theirs, because for us living by faith is not a life or death matter like it will be for them.
