Here is a question that was asked in a Christian and Atheist debate group that I am involved in administering, “If a rebellion took place in heaven, it means sin or bad things can happen in heaven. This is in contradiction to a God who is perfect and can only have good around him. Does this mean that sinners can go to heaven or that people can sin in heaven?”
In reflecting on this I think the scriptural answer is something important to all of us as believers and right after I decided to write on the matter it came up in an apologetics group that I participate in. There are important elements in the questions. A simple answer to one question is that no, sinners cannot go to heaven. The other part gets at whether sin and free will are compatible when we step from time into eternity. I have heard this part of the question asked a number of times.
We start by addressing sin, if we look at what Paul taught in Romans 6-8 we see the struggle of the believer with sin and we also see the solution, walking with and being led by the Spirit. Earlier in his ministry Paul put forth this same solution in his first letter, Galatians (see chapter 5). This is the case because even though we become a new creation at conversion, there is still a propensity toward sin in our physical bodies. Now to more detail.
We begin with what took place at conversion.
17 Therefore, if anyone is in Christ, he is a new creation; old things have passed away; behold, all things have become new. 2 Corinthians 5:17 (NKJV)
21 For He made Him who knew no sin to be sin for us, that we might become the righteousness of God in Him. 2 Corinthians 5:21 (NKJV)
We received a new nature at conversion. Our spirit was reborn. Yet when we read Paul’s letters it is evident that believers still struggle with sin. Paul’s heart cry is found in Galatians.
19 My little children, for whom I labor in birth again until Christ is formed in you, Galatians 4:19 (NKJV)
Paul wanted to see believers reflecting Jesus’ character, their new nature. In 1 Thessalonians 5:23 Paul’s prayer for the Thessalonian believers was that their spirit, soul and body would be preserved blameless at Jesus return.
To understand, when we dig a little deeper, we see the solution to our problem. At conversion we receive Jesus’ nature in our spirit. It is sanctified. As we continue in our walk our soul (mind, will and emotions), should progressively express Jesus’ nature, as Paul prayed in Galatians 4:19. I don’t think any of us will achieve perfection in this life, but we can increasingly look more and more like Jesus. Then finally at Jesus return we will be caught up into the air with Him in glorified new bodies, or be resurrected with glorious new bodies (1 Thessalonians 4:14-17, 1 Corinthians 15:39-49). At our resurrection or translation, we receive a glorified incorruptible body. There will only be one thing missing, a propensity to sin!
19 For the good that I will to do, I do not do; but the evil I will not to do, that I practice. 20 Now if I do what I will not to do, it is no longer I who do it, but sin that dwells in me. Romans 7:19–20 (NKJV)
Now we can answer the questions, “Does this mean that sinners can go to heaven or that people can sin in heaven?” No, sinners cannot go, only saints, and while theoretically we could sin, with sin removed we will have no desire to do so!
