The price of attonement???

[Godscreated]

If Christ had sinned He would have known He could not be the perfect sacrifice, so why would He have suffered through the crucifixion?

To trick you that he was sinless and make you buy the story that he was the perfect sacrifice.

What possible reason would He want to trick anyone, that makes no sense to me?

He also would have had to know the Father would not have raised Him from the Grave.

Well what if he could raise himself being God or 1/3 of God and all?

Again, why would God want to trick anyone, an omniscient and omnipotent being would have no reason to trick humanity. The God Head (Yahway) could not go against itself, Jesus addressed this very thing when the pharisees called Him satan. The God Head is of one mind in three persons. This is what Jesus said about a divided kingdom.
Matt. 12:25 And knowing their thoughts He said to them, "Any kingdom divided against itself is laid to waste; and any city or house divided against itself shall not stand. 26) "And if Satan cast out Satan, he is divided against himself; how then shall his kingdom stand? 27) "And if I by Beelzebul cast out demons, by whom do your sons cast them out? Consequently they shall be your judges. 28) "But if I cast out by the Spirit of God, then the kingdom of God has come upon you.
This statement show that Jesus could not go against the Father.

There are also many scriptures stating God can not lie.

But if God can sin, surely he can lie. So he can be lying about not being able to lie

If God lied He would sin, God says He will not be in the presence of sin, this eliminates the possibility of God sinning, god could not live with Himself if He sinned. This is another way through scripture to show God does not lie.
