Will Humans Have Freewill in Heaven?

[Drich]

Free from what should be you question... If you had (or simply kept reading) you would clearly see that the freedom Jesus was speaking of was freedom from sin and the consenquences of sin.

33 They answered, “We are Abraham’s descendants. And we have never been slaves. So why do you say that we will be free?”

34 Jesus said, “The truth is, everyone who sins is a slave—a slave to sin.

I see you conveniently left out verse 35

35 Now a slave has no permanent place in the family, but a son belongs to it forever

Jesus doesn't free people from slavery to sin to make them slaves to himself but to make them sons. So he is still disagreeing with Paul.

Though I have yet to meet the Christian who does not sin so this is yet another false promise.

Now ask yourself what is a son of God. Jesus is the Son of God, but obviously this is not what is being discussed. Jesus gives us incite to what He means if you read the rest of the chapter when He is speaking about who the father of the pharrisees is and what they must do to earn that title. In kind the same applies to the 'sons' of God. We also see in the very definition of the word huios (the word used for sons) in this application this context it describes not only the joy a child would experience with their parent but unwavering obedience and devotion to God.

D:
those who revere God as their father, the pious worshippers of God, those who in character and life resemble God, those who are governed by the Spirit of God, repose the same calm and joyful trust in God which children do in their parents (Rom. 8:14, Gal. 3:26 ), and hereafter in the blessedness and glory of the life eternal will openly wear this dignity of the sons of God. Term used preeminently of Jesus Christ, as enjoying the supreme love of God, united to him in affectionate intimacy, privy to his saving councils, obedient to the Father's will in all his acts

While Christ truly offers a place as a 'son' of God, we will still be expected to put the will of the Father over that of our own just as He did on the cross.
