What will we be doing in the New Heaven and New Earth?

So this question is a bit dependent on where you will be or more appropriately, where the Lord will have you working geographically after the final battle with Satan. The Old Testament prophets are fairly consistent with their descriptions of what is happening during the millennial reign of Christ (global recognition of the Lord and Yeshua, rebuilding, decontamination, global honoring of the feasts and festivals, etc...)

However the descriptions for when the Lord is "making all things new" is a bit scant comparatively when you realize it is eternity versus the small amount of time that directly preceded it (a mere 7000 yrs approximately).

It is important to understand the narrative in Revelation is the culmination of God's plan to reconcile humanity back to Him. The original plan was to have mankind as a steward over the Earth,…

So this is the introduction to the wonderful world of Linguistics and word etymology (it can be bland and boring, just a warning). Most of this is from memory, so let me know if I misremembered anything.

Hebrew / Greek / Germanic-Scandinavian / English

SHEOL / HADES / HEL / HELL

The words Sheol, Hades and Hel have approximately the same meaning and usage for their respective cultural-language groups, they are all referencing the underworld where souls go after death.

Curiously Sheol and Hel both have the grave as an entrance to the underworld. All the underworlds are down in the earth, beneath the ground.

Most modern translations will spell out "the grave" or "death" rather than use the Hebrew word Sheol in the Old Testament. The same is typical when the Greek word Hades is used in the New Testament, except substituted with Hell.

Just wanted to mention this when we were discussing the 144,000 praising God in front of his throne last Wednesday, it appears to indicate they will be praising him while still on Earth, not in heaven.

Jer 3:17 At that time they will call Jerusalem The Throne of the Lord, and all nations will gather in Jerusalem to honor the name of the Lord. No longer will they follow the stubbornness of their evil hearts. 18 In those days the people of Judah will join the people of Israel, and together they will come from a northern land to the land I gave your ancestors as an inheritance.

Who is "he who now letteth" in Paul's epistle to the church at Thessaloniki?

The Restrainer Is Removed

2 Thessalonians 2:6-7   And now ye know what withholdeth that he might be revealed in his time.  7 For the mystery of iniquity doth already work: only he who now letteth will let, until he be taken out of the way.

The Apostle Paul is a bit cryptic in this verse in 2 Thessalonians regarding the restrainer has sparked diverse interpretations among biblical scholars and theologians. Thereby leading to a variety of differing interpretations among Bible students, scholars, and theologians. The verse in question is part of a larger passage discussing the coming of the "man of lawlessness" which I have identified as the "Antichrist."

The passage discusses the anticipated arrival of the 'man of lawlessness,' commonly associated with the 'Antichrist.' The phrase 'he who now letteth,' as rendered in the King…
