Many of Paul’s references to heaven repeat what we have seen elsehwere. Thus:
Gal. 1:8 But even if we or an angel from heaven should preach a gospel other than the one we preached to you, let that person be under God?s curse!
Eph. 1:10 to be put into effect when the times reach their fulfillment?to bring unity to all things in heaven and on earth under Christ.
Eph. 3:15 from whom every family in heaven and on earth derives its name.
Eph. 6:9 And masters, treat your slaves in the same way. Do not threaten them, since you know that he who is both their Master and yours is in heaven, and there is no favoritism with him.
But this text adds a bit to our sketch:
Eph. 4:10 He who descended is the very one who ascended higher than all the heavens, in order to fill the whole universe.
If the first four emphasize heaven as God’s abode or as paired with earth to encompass the universe, Eph 4:10 adds something to this: Here we find Christ ascending above the universe: “higher than all the heavens.” The language strikes an image of the superiority and dominion of Christ over all creation. It also suggests more than one heaven: that is, probably back to the three of 2 Cor 12:2 (or even more).
A christological note: what is normally ascribed to YHWH is here described to Christ.
