A while back, I read something you wrote about Tribulation saints NOT sealed by the Holy Spirit, but recently, I happened upon something in my reading Revelation. In Chapter 9, it talks about the plague of locusts, with tails of scorpions. And the locusts are sent to sting ONLY those who DON’T have the seal of God in their forehead. (Revelation 9:4). Is that different than being sealed by the Holy spirit? If so, how?
The seal spoken of in Rev. 9:4 is not the same as the one the church receives. In the first place, it relates to Rev. 7:3-4 where it says the only ones who will have the seal of God in their foreheads are the 144,000 from the tribes of Israel. No one else, whether believer or not, will receive the seal. Second, the purpose of that seal is to protect the 144,000 from the locusts. It’s not intended to guarantee their salvation, like the seal we have does for us (2 Cor. 1:21-22).
