I was taught the NT is infolded in the OT, and the OT unfolds in the NT. Types and shadows, God's ways.
Probably easier to win the lottery than find a Bible teacher that can teach those things. I've known one in 33 years.
I agree.
I have always considered the fact that both the Old and New are Testaments/Covenants. The same as last will and testament.
The Old Testament was a Covenant between the Hebrew people and God. They agreed to worship, sacrifice to, and serve Jehovah God in exchange for his blessing them with peace and prosperity in the world.
That Old Convenant was established upon certain agreed upon written laws between God and the Hebrew people:...….
1. Obey and be blessed, disobey and be cursed.
Because all the world were living in a condition contrary to God's created intention, and as the history shows, they FAILED.
As the Old Testament closes, we see that they were committing more sins than their pagan neighbors.
So then, That Old Test. covenant was null and void by their disobedience.
The New Covenant is not based on mankind's ability to perform. God has initiated a covenant with those who "believe" he is able to declare righteous those who come to him through Jesus Christ, whose death on their behalf, for their salvation, was his last will and testament.
Those who come to God via this covenant inherit all that Christ God's son, in all of his riches and glory has bequeath to them.
Ephesians 1:17-20......
"That the God of our Lord Jesus Christ, the Father of glory, may give unto you the spirit of wisdom and revelation in the knowledge of him: The eyes of your understanding being enlightened; that ye may know what is the hope of his calling, and what the riches of the glory of his inheritance in the saints, And what is the exceeding greatness of his power to us-ward who believe, according to the working of his mighty power, Which he wrought in Christ, when he raised him from the dead, and set him at his own right hand in the heavenly places".
The Old is old, because there is Now a better Covenant.
