I am confused about the 144,000 and the two witnesses. Which one came first, the two witnesses, did they witness to the 144,000? Or did the 144,000 witness the to the two witnesses? Will these two witnesses preach during the last half of the Tribulation? Will the 144,000 have any ministry during the last half of the Tribulation?
I believe the Book of Revelation is for the most part a chronological account. The 144,000 witnesses are first mentioned in Rev. 7:1-8, while the 2 witnesses don’t appear until Rev. 11:3. That means the 144,000 will arrive first. There is no apparent connection between the two groups. Both will be prepared for their respective ministries independently. The 2 witness will serve from just before the beginning of the Great Tribulation until just before its end. The Bible doesn’t offer any detail on the duration of the ministry of the 144,000. Nor does it inform us about their final disposition.
