Satan wanted to get Jesus to proved
He was the Son of God by tempting
Him into turning the stones to bread.

But after a long fast there are feelings
of spiritual power even in physical
weakness.

Jesus came to do the Father's will and
not His own. So Jesus answered him
"....man doth not live by bread only,
but by every word that proceedeth out
of the mouth of the LORD ....."
Deuteronomy 8:3

It had nothing to do with Jesus' ability
to turn the stones into bread, It was
His desire to do the Father's will.

He miraculously feed multitudes.
