Question:
What happens during the rapture?  Will unbelievers have a second chance to be saved?

Answer:

We read 2 Thessalonians 2:1-12 to show that those who had rejected the Gospel of Jesus Christ will have no second chance to be saved, but the Lord will send a strong delusion that they might believe Satan’s lies.  It is so important to believe on the Lord Jesus now, before it’s too late.
