There must be something wrong with this passage then:
Heb 5:
7During the days of Jesus’ life on earth, he offered up prayers and petitions with fervent cries and tears to the one who could
save him from death,
and he was heard because of his reverent submission.
8Son though he was, 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.
1. No one is being saved from physical death but salvation is about spiritual death. So God had to be saved from physical death according to you? And was Jesus even saved from this so called physical death according to you?
2. The position, 'without sin/ righteous' is also what men are turned to, for salvation; and i don't mean men are being turned to God. So saying Jesus is God and could not be saved is neither here nor there.
3. Did Zacchaeus need the gospel for his salvation?
