We are not like God- we had a beginning. Other than Adam and Eve, I believe it is when He “knit us together in our mother’s womb.” Sperm doesn’t have a soul, an egg doesn’t have a soul, but God made those two become one person. And mankind can never separate the dna of a father from the dna of a mother once a child (soul) is conceived.
Sin is not physical. It is a decision. Satan fell from heaven because he sinned, there is no physicality in heaven. This is why Jesus said if you hate your brother you are a murderer- whether you physically carry it out or not. He said the same for an adulterer. The bible says sin is knowing the good you ought to do but choosing not to do it.
What do you think being made in God's image means? We have an eternal soul because of it. We are able to think somewhat like God because of it and he didn't want robots. The problem being that an eternal soul has to end up somewhere ..either Heaven (Peace, Order) or Hell (Sin, Disorder).
You are suggesting we will be able to "hate" in Heaven. How?
