I think you are missing something very obvious.....no one went to heaven before Jesus. (John 3:13)
King David did not go to heaven. (Acts 2:34-35)
Elijah did not go to heaven.
Elijah was carried up out of Elisha’s sight by the windstorm but the Bible does not say that Elijah died on that occasion. As a matter of fact, Elijah was still alive and active as a prophet at least five years later, apparently over in the territory of Judah. The Bible tells us:
“Eventually there came a writing to [Jehoram, king of Judah] from Elijah the prophet.” This letter foretold the sickness and death of Jehoram because of his idolatrous course. (
2 Chronicles 21:12-15)
A further evidence that Elijah did not die at the time of being taken into the “heavens” is that his servant and successor Elisha did not then hold the customary period of mourning for his master. (Compare
2 Samuel 19:1; 1 Chronicles 7:22; 2 Chronicles 35:24)
So you see, according to Jewish belief the dead were in "sheol" which is the grave...a place of complete inactivity and unconsciousness. (Ecclesiastes 9:5; 10) There was no belief in an immortal soul in Jewish teaching until the Pharisees adopted it from the Greeks. Christendom did too. But Jesus taught that the dead are all still in their graves since he says that he will call them from their tombs in the resurrection. (John 5:28-29) Paul too stated that this was Jewish belief. (Acts 24:15)
Where do people get the idea that all Christians are going to heaven? There are only a chosen few granted that privilege and for a specific purpose.....to bring humanity back into an approved relationship with God through the ministry of the reconciliation.
2 Corinthians 5:18-20...
"But all things are from God, who reconciled us to himself through Christ and gave us the ministry of the reconciliation, 19 namely, that God was by means of Christ reconciling a world to himself, not counting their offenses against them, and he entrusted to us the message of the reconciliation.
20 Therefore, we are ambassadors substituting for Christ, as though God were making an appeal through us. As substitutes for Christ, we beg: “Become reconciled to God.”
That is the whole mission of Christ and his kingdom....what was lost in Eden is restored in Revelation. (Revelation 21:2-4) God put humans on earth, not in heaven. Those chosen for rulership in heaven are the "ambassadors" who carry out "the ministry of the reconciliation". Ambassadors must be appointed by their ruling authority. It is not a position that they can give themselves. They also need qualifications.
At the time Jesus said that there was no human who had gone to heaven. John was dead. Jesus had not yet been executed so the way through the "curtain" was not even open. (Hebrews 10:20)
Only the ones taken into the new covenant will rule with Christ in heaven. Since they will be both rulers and priests, (Revelation 20:6) if everyone goes to heaven, who will be their subjects? For whom will they be priests?
1 Corinthians 15:20-24....
" But in fact Christ has been raised from the dead, the firstfruits of those who have fallen asleep. 21 For as by a man came death, by a man has come also the resurrection of the dead. 22 For as in Adam all die, so also in Christ shall all be made alive. 23 But each in his own order: Christ the firstfruits, then at his coming those who belong to Christ. 24 Then comes the end, when he delivers the kingdom to God the Father after destroying every rule and every authority and power."
Can you see the order presented here....Christ is the "firstfruits", then "at his coming" those who "belong to Christ". That doesn't include those who died before Jesus. These ones believed in a resurrection back to life on earth. I believe that too. I will not go to heaven but look forward to the benefits that the Kingdom will bring to all mankind.
