The general Christian view is:
God chooses people to rule with him in Heaven who believe him.... between Calvary and the Great Tribulation time period.
Christ gathers all the gentiles (and some converted Jews) who believe during the church age (times of the gentiles). Those still alive at Christs return "in the clouds" are evacuated to heaven (the 1st resurrection) just prior to the Great Tribulation.
Then Jehovah reserves for himself 144K Israelites as a co-ruling class.... probably on earth (not as clear on this point).
One is the Bride of Christ. The other is like a wife to Jehovah. (Remember that the New Covenant did not void the Old Covenant. The New Covenant is described as a better covenant.)
Both groups rule with God during the Millennium over these groups:
1. Other believing Jews found at the end of the GT
2. Believing Gentiles found at the end of the GT who did not join the Antichrist to kill the Jews (Christs Brothers)
These people enter the kingdom millennium on earth but are not immortal, can die, and can still pass on the sin nature to their children.
At the end of the Millennium the age old question of nature vs. nature will have been answered, since many will still choose the sin nature over God, in spite of perfect government and peace.
I am a Christian believer. And, I don't feel qualified to rule with Christ. But my feelings are not what guides my decision making. God's word does.
People who get themselves in agreement with God now regarding abandoning the sin nature, apparently are given high priority and greater responsibility with God, whether they feel like they deserve it or not.
