In Jesus, God fully experienced humanity including temptation that was real. That is not cheating, the temptations were real, he could have failed, but he didn’t
7During the days of Jesus’ life on earth, he offered up prayers and petitions with loud cries and tears to the one who could save him from death, and he was heard because of his reverent submission. 8Although he was a son, he learned obedience from what he suffered 9and, once made perfect, he became the source of eternal salvation for all who obey him 10and was designated by God to be high priest in the order of Melchizedek.Hebrews 5:7-10
I would argue that God didnt "need" to experience temptation. After all, he made us and is omniscient. Could Jesus really sin (note: I think he did sin)? With a god-man nature I would say it is impossible. Being 100%G100%M the 100%G would not permit sin to occur. How could it? If the man part sinned the God part would, by definition, also sin.
He clearly would not be like "us" and therefore is cheating.
The writer of Hebrews claims Jesus is the High Priest but he is not of the correct tribe. Jesus is presumed to be of the tribe of Judah (which is debateable) and therefore could not be of the Aaronic Priesthood.
