Doubting doesn't mean God was separated from himself. Jesus was also fully human so of course he was capable of doubting.
God opening the Holy of Holies was an indication of the change that had just taken place - there was no longer a need for priests and temple sacrifices.
Great wonders...
That's your misunderstanding of what Jesus meant by quoting that scripture. He may have felt abandoned in that moment but he wasn't.
If you read the rest of the Psalm you understand that it ends with Jesus not being forsaken:
"For he has not despised or abhorred the affliction of the afflicted...
That just shows Jesus is humble.
You know one of Jesus's names is everlasting Father?
"For to us a child is born, to us a son is given, and the government will be on his shoulders. And he will be called Wonderful Counselor, Mighty God, Everlasting Father, Prince of Peace."
I don't claim to...
It's still free will.
I'm free to ignore warnings and jump into deep water even if I can't swim.
Actions having consequences does not negate free will.
For even if there are so-called gods, whether in heaven or on earth (as indeed there are many “gods” and many “lords”), yet for us there is but one God, the Father, from whom all things came and for whom we live; and there is but one Lord, Jesus Christ, through whom all things came and through...
I disagree.
If a dog or toddler is never made to understand that some behavior is unacceptable you will end up with a person or animal that can't control themselves.
The important thing to understand about demons is that they understand the power of Jesus name.
They are nothing to play with but if you are under attack, the best offense is praying against them in Jesus name. You must be completely sincere, however.
No. They go back to the dirt. That's all
They aren't exactly innocent either, they are amoral.
And you can certainly teach an animal by using punishment.
I'm not sure how anyone could no longer feel guilty over something so evil. I'm not sure they should ever get over it.
I support the death penalty in such cases. I think giving a life for other innocent lives is justice.
