You haven’t read the Book of Revelation?
I’ve understood that everyone, that is EVERYONE will experience the tribulations mentioned.
I’ve not only read Revelation but studied it extensively. Faithful believers do not experience God’s wrath. Many promises are given in scripture to believers that they will escape the wrath to come. Its current unbelievers who will experience that wrath just as unfaithful Israelites were punished by God and then returned to Him. It will cause some to repent and be killed but current faithful believers are promised to be kept from that wrath.
