Sin in Heaven?

Some erroneously claim that people will be able to sin in heaven. The only argument I have heard that even comes close to referencing a Bible verse for this claim is that sin is a possibility in heaven because Satan sinned in heaven. This is usually just an argument to appeal that we will have free will in heaven. I have previously discussed free will in general here and free will in heaven here. Sin cannot be in God's presence, which is why he made hell. Hell is just being away from God. There is no sin in heaven, because it is the place where the sinless God dwells. Since sin separates us from God, being reunited with God gets rid of our sin.

Those who have been cleansed in the blood of the Lamb have been cleansed forever. There is no more death in heaven, the result of sin. We die once and then the judgment. Our death ends sin, the Scripture says. Just as the good angels are fixed in their sinless state now, so also we shall be. We will serve God forever willingly, but it will be impossible for us to will to sin as did our first parents. In heaven it will not be like in the beginning of our human history. Old things have passed away, the new has come (Revelation 21:4). There will be only life, eternal life, and where there is eternal life there is eternal sinlessness. Rest your soul on that and praise God for His great goodness in giving us a sinless Savior. Also, it is important to remember that we will not be in heaven forever, but living bodily in the new creation, in which there will also not be sin for all of the same reasons.
