I think a clue is to be found in Paul's remarks in Ephesians chapter two:
Ephesians 2:1 And you
hath he quickened, who were dead in trespasses and sins;
2 Wherein in time past ye walked according to the course of this world, according to the prince of the power of the air, the spirit that now worketh in the children of disobedience:
3 Among whom also we all had our conversation in times past in the lusts of our flesh, fulfilling the desires of the flesh and of the mind; and were by nature the children of wrath, even as others.
4 But God, who is rich in mercy, for his great love wherewith he loved us,
5 Even when we were dead in sins,
hath quickened us together
with Christ, (by grace ye are saved
6 And
hath raised us up together, and made
ussit together in heavenly
placesin Christ Jesus:
7 That in the ages to come he might shew the exceeding riches of his grace in
his kindness toward us through Christ Jesus.
8 For by grace are ye saved through faith; and that not of yourselves:
it is the gift of God:
Paul says we are already at the throne of God if we are IN Jesus Christ. We are in Christ; Christ is at the throne of God, therefore we have access to God NOW, not in a thousand years.
