Rebellion means defiance, disobedience, insubordination, The Bible calls Rebellion as the sin of witchcraft. 1 Samuel 15:23.
In Israel's time, a rebellious son was stoned to death. Deuteronomy 21:18-21. Evidently rebellion is a serious matter, if it was serious then to require death, it is serious now but not the death penalty but when Christ shall come the rebellious ones will receive their punishment.
Ezekiel 20:8 "But they rebelled against Me and would not obey Me."

Have you ever known a rebellious person? I have and you cannot reason with them at all. Your very fortunate if you can even get a word in, they are so sure that they are right in their rebellion. It is the saddest thing I have ever encountered. If you have never known anyone rebellious, you are very blessed. I feel so sorry for the rebellious person, they do not know what they are doing to themselves let alone others that love them. It is a fearful thing to fall into the hands of the living God if you are in rebellion against Him and His word, a fearful thing. The only thing you can do is pray for them. I do that daily and sometimes more. Love them anyway, that's what God says to do. Love your neighbor as yourself. Love and Pray is God's way. Grandma Joan
