I dissagree with the premise that no man can hurt God because of his greatness.
Where there is great love, there can be great hurt.
I believe that being able to feel pain and hurt are part of being made in God’s image.
There is every reason to believe that Christ’s pain when he wept over Jerusalem, and in the garden when he sweat drops of blood, and on the road to Golgotha, and on the cross were all real.
That is true the God-Man Jesus Christ could feel pain.
