I suspect that this jasper has an agenda.
My nephew goes to this blasphemer’s church.
OT context is critical to authority of NT — fulfillment of prophecy, etc.
The Bible tells of two time periods, but only one God.
The theme of the Bible is the coming of The Msssiah the Lord Jesus, and His Kingdom of Righteousness and Peace. The purpose of the Bible, all of it, is to show God's Plan of Salvation and Reconciliation with His Created humans.
Nothing more. Nothing less. Nothing else.
They all do. Te OT is full of history and prophesy esp. prophesies pointing to the coming of Yeshua.
