My colleagues have had many discussions about this verse. I am teaching Isaiah in a bible study, and I want to be able to teach it correctly. Thank you so much. I catch your program on Direct tv 367 as often as I can, which is almost every Saturday night.
I will tell you what I believe Isaiah 65:20 is talking about. Beginning in verse 17 the Lord, speaking through Isaiah is prophesying the future blessings upon Israel. Remember, this begins for them first in the Millennial Kingdom and extends into the Eternal Kingdom. In that 1000 year reign, it appears that a rebellious child will be given till he is 100 years old before being put to death as taught under the law in Deuteronomy 21:18-22. In Moses day, God judged the Nation in the wilderness from 20 years old and up, so that those 19 and under were considered children. In the Millennium, when people will live the whole 1000 years, or as Isaiah 65:22 says “for the days of a tree are the days of my people,” a child is anyone under 100 years old and the age of accountability is age 100.
