Resurrection verses Reincarnation

What are we seeing here sonship, God changing his mind, God revealing imperfections, the divine ability to cause fault?......Or are we just seeing a biblical contradiction?

Sometimes we see God changing His mind without changing His will.

From Genesis on we see every kind of obstacle erected against God accomplishing His eternal purpose to dispense Himself into man's being. But the story of the Bible is God branching over these walls. He cannot be stopped.

From the divine perspective we can only give Him some little difficulty. But we cannot stop His will from rolling out of eternity to accomplish His plan to join Himself "organically" with man and man with Him.

"So why did they not offer lambs and goats everlastingly? " someone asks.
Christ is the end of the law in that regard. He is the final offering of the Son of God as the Lamb of God - the God incarnated human lamb for the eternal redemption.

But redemption is not an end in itself.
Forgiveness is not an end in itself.
God still has a purpose with forgiven man to dispense His life and nature into man.

Briefly now, Paul says that the righteous requirement of the law is then fulfilled in the redeemed who walk not according to the fallen and weak flesh but according to the Christ indwelt regenerated spirit of man.

"For that which the law could not do, in that it was weak through the flesh, God sending His own Son in the likeness of the flesh of sin and concerning sin, condemned sin in the flesh,

THAT ... the righteous requirement of the law might be fulfilled in us, who do not walk according to the flesh but according to the spirit." (Rom. 8:3,4)

This is about God dispensing His life through Christ, by the Spirit into man for a blended and incorporated union.
