You get rid of the OT and you get rid of Jesus it's just that simple.

"Then he said unto them, O fools, and slow of heart to believe all that the prophets have spoken:
Ought not Christ to have suffered these things, and to enter into his glory?
And beginning at Moses and all the prophets, he expounded unto them in all the scriptures the things concerning himself." Lk24:25-27

I use discernment and i connect directly to Jesus.

Yes indeed discernment is greatly needed to grasp the immensity of Truth the Bible provides. It's the OT by which mankind even knows about Satan and the great conflict between him and God's son that the entire of world history would be about.
The OT prophetic accomplishments (to the degree of mathematical impossibility to achieve coincidentally or artificially) establish it's veracity along with archaeological discoveries. Creation science is now to the point that supports a literal 6/24hr day creation.
On and on.
Nope the very 'big G' God brought that book into existence and has watched over it.
In spite of all the hanky panky that He has allowed His enemies to conspire against it it's still "given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness" 2Tim3:16

Unto salvation .. amen.

We can disagree
