I don't think it could be made any clearer than this. There will be a group IN HEAVEN and a group ON EARTH that will be gathered together IN ONE. In the DISPENSATION OF THE FULNESS OF TIMES. Now, who are those that are the IN HEAVEN group? Those who are "Blessed with all spiritual blessings IN HEAVENLY PLACES IN CHRIST." Eph. 1:3. That would be US. The Church the Body of Christ. "If ye be risen with Christ, seek those things which are ABOVE, where Christ sitteth on the right hand of God. Set your affection on things ABOVE, NOT on things on THE EARTH."Co. 3:1,2.
So, who are those that are ON EARTH that He is going to gather together with US in heaven, in the dispensation of the fulness of times? "And Jesus went about all Galilee teaching in their synogogues, and preaching the GOSPEL OF THE KINGDOM"Mat. 4:23. "Blessed are the meek for they shall INHERIT THE EARTH." Mat. 5:5. "thy kingdom come. Thy will be done in EARTH, as it is in heaven." Mat. 6:10.
And on and on. Israel is God's earthly people. They will be a kingdom of priests and a blessing to all nations ON EARTH when Christ RETURNS to EARTH and sets up His KINGDOM ON EARTH.
We are NOT. The Church the Body of Christ has its promises and position in the heavenlies. And that is EXACTLY why we will be raptured at the end of this dispensation of grace. To begin our promised position in the heavenlies.
It can be argued about until pigs fly. But it doesn't change God's word one iota. The covenants He made with Israel will NOT be left undone. Or changed. Or given to another group. WE ARE NOT ISRAEL.
That nails the truth in a nutshell of God's different purposes and plans for the Church and Israel better than I've seen!
Awesome!
