All of Mankind inherits a rebellious nature because of the fall and because we are born into a sinful world ... ALL will indeed sin.
Humans didn't receive a "sinful desire" directly implanted by Satan; instead, they were tempted to choose sin, and the consequences of that choice the sinful nature and became part of their heritage ...
All mature adults will sin, but that does not require any change in our “nature”, since we had, from scripture, a change in knowledge and not nature, so are you defining this change in “knowledge” as a change in nature?
Scripture does not even suggest man “inherited a new rebellious nature”, but we did gain knowledge of good and evil, so is knowledge itself bad?
Adam and Eve with the nature they had and only one way to sin, sinned, so why would our nature have to change with knowledge of tons of ways to sin, for us to sin?
Eve had a desire to eat from the tree without the serpent speaking up, so now do you want to add Adam and Eve with satan to your list of what caused you to sin?
the desire to sin will be gone in heaven because glorified believers will be completely transformed to be like Christ, free from the sinful nature, and in God's presence where sin cannot exist; we will have free will but only to choose what is right and holy, with no temptation or internal pull towards evil. Our nature will be purified, our wills aligned with God's, and the ability to sin will be removed as part of complete redemption, similar to how God Himself cannot sin (no we will not be gods, not suggesting this)
Is sin the problem or is it unforgiven sin, which is the problem?
What is your answer for why God allows people to sin and why He allowed satan into the Garden?
Everything that is happening and God is allowing to happen seems to be in order to help willing individuals (including Adam and Eve) in fulfilling their earthly objective.
God gave Adam and Eve a clear warning and a choice (free will) .... if you eat of the tree you will die ... satan said you will not surely die. Eve believed a lie (deceived). Eve allowed Satan's lie to overshadow God's truth, believing Satan that she wouldn't die but become wise like God. There won't be any lies in heaven.
Specifically, the Bible gives us the reason Eve ate and it was not because she believed satan, look: “6 When the woman
saw that the fruit of the tree
was good for food and
pleasing to the eye, and also
desirable for gaining wisdom, she took some and ate it.”
It was all what the woman desired and not because she believed satan, but satan did help her carrying out her sinful desire.
John 1
8If we say we have no sin, we deceive ourselves, and the truth is not in us. 9If we confess our sins, He is faithful and just to forgive us our sins and to cleanse us from all unrighteousness. 10If we say we have not sinned, we make Him out to be a liar, and His word is not in us.
We are constantly being sanctified by the Lord, with His help we can do much better but we will never be perfect (without sin) until Jesus returns
True sinless perfection is only achieved at the Second Coming when believers are glorified, but this doesn't negate the present call to grow in Christ by the Holy Spirit, striving for character transformation, and being "perfect" (complete) in Him now*,* through faith, even while acknowledging our ongoing struggle with sin until the end. It's about a present, empowered process of sanctification, not a future, human-achieved state, emphasizing dependence on Christ for completion.
Read further: 1John 2: 1 My dear children,
I write this to you so that you will not sin.
But if anybody does sin, we have an advocate with the Father—Jesus Christ, the Righteous One.
Yes! All mature adults do sin, but John talks about in the future and is writing this so they might not sin again and makes future sins strictly contingent with “but if” and not “but when”.
** Imputed Righteousness: Through faith in Jesus, believers are clothed in His perfect righteousness, making them legally perfect in God's eyes.
I do not believe Adam and Eve’s sin was imputed on us (we all sin) and I do not see Christ’s righteousness being imputed on us.
Philippians 1:6
AMP
I am convinced and confident of this very thing, that He who has begun a good work in you will [continue to] perfect and complete it until the day of Christ Jesus [the time of His return].
"Jesus was “tempted” while here on earth, so why can we not be tempted in heaven and not sin like Christ avoided sinning?"
True .... tempted by who? Satan .... Satan (the tempter) will be destroyed and God does not tempt anyone. Jesus was the only one who did not fall unto temptation that's why he is our savior ... He never sinned.
Again, satan is the tempter ... NOT God and satan will be completely destroyed and when we are glorified we will have a complete sinless perfection
Now think about this ... If Adam and Eve had never been tempted ... would we be in this mess? No we would not.
If the whole problem is with satan in the Garden, then why did God allow satan to be there?
We can see satan’s purpose for being in the Garden and roaming the earth, if we understand man’s objective, so what is man’s objective?
