Some 2000 years ago in the midst of Israel was the "tree" of Moses and the "tree" of Jesus.
One led to life and the other led to death.
In order to recieve eternal life one must surely die and be born again.
So both trees were necesarry for salvation.
Both trees are good for food.
Gen 2:9
And out of the ground made the LORD God to grow every tree that is pleasant to the sight, and good for food; the tree of life also in the midst of the garden, and the tree of knowledge of good and evil.
Moses was given the law of do's and don'ts. Jesus was given the keys of faith and grace.
You have to learn the do's and don'ts before you can use the keys of faith and grace.
But once you've learned the do's and don'ts you don't need them to lead you.
You master them. And then you walk by faith through grace.
Jhn 1:17
For the law was given by Moses,
but grace and truth came by Jesus Christ.
Gal 3:24
Wherefore the law was our schoolmaster
to bring us unto Christ, that we might be justified by faith.
Why were they placed in the center?
Luk 24:36
And as they thus spake, Jesus himself stood in the midst of them, and saith unto them, Peace
be unto you.
Mat 18:20
For where two or three are gathered together in my name, there am I in the midst of them.
Zec 8:3
Thus saith the LORD; I am returned unto Zion, and will dwell in the midst of Jerusalem: and Jerusalem shall be called a city of truth; and the mountain of the LORD of hosts the holy mountain.
Luk 2:46
And it came to pass, that after three days they found him in the temple, sitting in the midst of the doctors, both hearing them, and asking them questions.
Because God is in the center of everything, always.
Whether it be his law or his word.
His word is his law.
And everything flows from the center.
