Is God of the New Testament same as the God of the Old Testament?

Did God change from Old Testament or is it the Same God?

Let’s consider this from the perspective of an enemy of God who dies in his own sins. Will this person be annihilated, eternally tormented or Reconciled after His Banished time in Judgment (Punishment)?

God does not take away life = God does not annihilate life nor eternally torment any life

Even a banished one (cast out from Him) = not to remain such eternally = as He seeks ways to ‘Reconcile’ that ‘banished person’

As the verse below clearly implies:

“We will certainly die and be like water poured out on the ground, which can’t be recovered. But God would not take away a life; He would devise plans so that the one banished from Him does not remain banished.” (2 Samuel 14:14)

Best is, God doesn’t change to become an annihilator nor an eternal tormentor later.

His first state as a “Reconciler” as the ancient quoted verse remains even toward a person who “Died” (please notice the word ‘die’ in verse above) and became “estranged” or “banished” or “cast out” or “separated” from Him.

He makes ways to “Reconcile” back as Scripture agrees Beautifully to this Same Unchanging God in verse below too

“and by Him to reconcile all things to Himself, having made peace by the blood of His cross through Him, whether the things on the earth or the things in the heavens.” (Colossians 1:20)

Peace to you
