CRAZYGUY said - "You make a good point Perry, but why then does Paul talk so much about a heavenly calling?"
I puzzled over Paul's wording, so I looked at the the original Greek to see if maybe something had been lost in translation and his actual context had been skewed. Here it it is:
(Hebrews 3:1) Consequently, holy brothers, partakers of the heavenly calling (invitation - footnote in NWT)
heavenly - epouranios (adj) - of heavenly origin or nature. (The ORIGIN of the invitation)
(Philippians 3:14) I am pursuing down toward the goal for the prize of the upward call of God by means of Christ Jesus.
upward - anō - up, upwards, above, on high
call - klēsis - a calling, calling to, a call, invitation, to a feast, of the divine invitation to embrace salvation of God.
Was Paul simply reminding Christians of the the sourceof the invitation to all men to gain salvation through Christ, (heaven) rather than claiming it was the destination?
If heaven is the destination, then the promises at Psalm 37:9-11, 29 ("And they will reside forever upon it") Revelation 21:3,4 (Tent of God is with mankind, who will have no more pain, death etc.) and other descriptive verses, become very confusing and create problems as to what is actually being promised!
