Will it be possible to sin in heaven?
Boy, talk about tough questions! But the fact I cannot answer this question does not prove one way or another, none of us will know what heaven is like until we get there.
I do not think we will ever want to sin in heaven because we have already made our choice for good here in this life. We have already experienced rebellion and sin and seen the consequences. Frankly, I do not want to sin NOW, but at the same time I am at times drawn to sin. This is the lust of the flesh which we will not know in heaven.
But the scriptures give a few glimpses of heaven that do not show us like mindless robots.
Rev 6:9 And when he had opened the fifth seal, I saw under the altar the souls of them that were slain for the word of God, and for the testimony which they held:
10 And they cried with a loud voice, saying, How long, O Lord, holy and true, dost thou not judge and avenge our blood on them that dwell on the earth?
11 And white robes were given unto every one of them; and it was said unto them, that they should rest yet for a little season, until their fellowservants also and their brethren, that should be killed as they
were, should be fulfilled.
Now, here are saints in heaven, and they sound as if they are impatient and complaining to a degree. They also want revenge. It seems they are given white robes to pacify them and they are told to rest. It seems they are being asked to be patient.
The scriptures say we should not complain.
Jud 1:16 These are
murmurers, complainers, walking after their own lusts; and their mouth speaketh great swelling
words, having men's persons in admiration because of advantage.
1 Cor 10:10 Neither murmur ye, as some of them also murmured, and were destroyed of the destroyer.
Now, these folks were not quite murmuring, murmuring is defined as complaining in secret, like as folks might complain about their boss at work behind his back, or even complain about their pastor at church behind his back.
Yet, they do seem to be complaining to a degree, and being impatient.
But again, none of us will know for certain exactly what heaven is like until we get there. I am sure we will all be in for a great many surprises.
