This was me just sharing what I believe. Obviously, not everyone will agree and that's okay. You shared what you believed as well, when you said there is a place where evil does not exist (heaven).
Luke 19:27: But those mine enemies, which would not that I should reign over them, bring hither, and slay them before me.
Exodus 22:20
“He who sacrifices to any god, other than to the Lord alone, shall be utterly destroyed."
Deuteronomy 17:2-7
“If there is found in your midst, in any of your towns, which the Lord your God is giving you, a man or a woman who does what is evil in the sight of the Lord your God, by transgressing His covenant, and has gone and served other gods and worshiped them, or the sun or the moon or any of the heavenly host, which I have not commanded, and if it is told you and you have heard of it, then you shall inquire thoroughly. Behold, if it is true and the thing certain that this detestable thing has been done in Israel, then you shall bring out that man or that woman who has done this evil deed to your gates, that is, the man or the woman, and you shall stone them to death. "
2 Chronicles 15:12-13
And they entered into a covenant to seek the Lord, the God of their fathers, with all their heart and with all their soul, but that whoever would not seek the Lord, the God of Israel, should be put to death, whether young or old, man or woman.
The Bible is quoted and used by Christians in and out of context (whatever that means) every day. Jesus may not have said it, but God commanded it. Their God commanded all of this. The same God that supposedly sent Jesus.
