No, I believe that probably Adam and Eve were closer to God than most believers I have known... that is before they disobeyed God. They could have been even closer still if they had partaken of the Tree of Life and left that other forbidden tree alone!
Rebirth is a new thing in Christ.
Adam and Eve being uncorrupted had fellowship with God, walking with Him in the garden. Scripture does not teach that they were indwelt by the Holy Spirit. Scripture teaches rebirth in Christ comes through His death and resurrection. Sins before the Law were overlooked, as sin is not imputed without Law. God holds us responsible for what He has told us.
Sins under the Law were covered by sacrifice, but not permanently removed. Only in Christ, the Lamb of God, are the sins of the world removed. Carried away by Christ.
Adam was uncorrupted, fellowshipping with God, until he disobeyed, and the corruption of sin began. Adam lost his fellowship with God, and lost his right to the Tree of Life. We don't know what his fellowship with God was like, I suspect that we can't really imagine or speculate on that very well.
Nothing in the Bible tells us that Adam was indwelt with the Holy Spirit, being joined to Christ. What the Bible does teach us is that we begin to share His life when we've shared with Him His death.
Adam began uncorrupted, we begin being corrupted by sin. God cleanses us from sin, justifies us - making us righteous - by immersing us into Christ in His death, and burial, so we can also share His resurrection life. Later, in our bodies, but now, in our spirits. Having been immersed into Christ, raised together with Him, we are joined to Him, receiving His Spirit.
We know we are in Him, and we know He is in us, by His Spirit given unto us. Our lives and Adam's life are very different things, starting in different ways, He fell from life to death. Did God's Spirit in Adam fail him? That's the problem with thinking that we and Adam are/were the same.
We aren't. Weren't.
We are
restored from corruption by sharing the death and resurrection of Christ, he
entered into corruption by disobedience. That very same corruption that is overcome by the power of a new life in Christ. The new life in Christ wherein God promises to overcome by our faith the power of the flesh, and the world, and all evil.
You question whether we may make the wrong choice as did Adam, whether we might fall from this life into death, didn't Adam fall from life into death? But our life is in Christ, who has promised, I will never leave you, nor forsake you.
So I continue to ask . . . do you believe this is true? That Jesus will NEVER leave you, NEVER forsake you?
If you believe His promise is true, that Jesus will in fact now never leave you, never forsake you, shall we not rejoice in His steadfastness? And hold the ever closer to Him in trust and love?
Much love!
