What is freedom?
Freedom is often seen as the free choice to do good or evil, to live God's way or break his will, to sin or be like Christ.But actually that can't be biblical freedom because in the New Creation we will all be free but there we won't be able to sin any more. There is no choice, not to love Jesus. There we will obey the will of God completely without any desire to do otherwise. So according to our common definition of freedom, we will have no freedom in Heaven at all. Unless this definition is of worldly origin and needs to be replaced.
Yes, in the New Creation we will be free because freedom is definite as being absolutely conformed to the image of Christ. Freedom is to act according to your nature. That means that God is free, to do according to his nature to be love. A non-Christian acts according to his nature - the sinful flesh. Yet he is not free but in slavery to sin. The Christian is enabled to freedom - he can act according to his new nature in Christ through the new birth but as long as he remains in the old, sinful body, he can slip into sin but will know that this sin is no freedom but something he hates doing. This new freedom becomes more and more evident, the more the will of God is revealed to him in Christ and he will see more clearly when and how he can be free, that is; like Christ. Hence it follows that Adam and Eve were almost free (sin not being in the world yet), but not completely since they still had a choice to transgress against the LORD's command and eat from the tree. If that choice had not existed, they would have had complete freedom.
In the New Creation he will finally be free and the sinful body will be replaced with the resurrection body. There he will be free, like Christ, free from making any decision to go against the will of God. That is true freedom.
(1Pe 2:16) Live as people who are free, not using your freedom as a cover-up for evil, but living as servants of God.
(2Pe 2:19)They promise them freedom, but they themselves are slaves of corruption. For whatever overcomes a person, to that he is enslaved.
On that day when freed from sinning
I shall see Thy lovely face.
Clothed then in the blood-washed linen
How I'll sing Thy sovereign grace.
Come my Lord, no longer tarry
Take my ransomed soul away;
Send Thine angels now to carry
