Nick, you are denying straight forward scripture, and then saying a passage says something that it does not. You are forcing the text to your belief.
You leave out the WHEN
7 Who in the days of his flesh WHEN he had offered up prayers and supplications with strong crying and tears unto him that was able to save him from death, and was heard in that he feared;
These were in the days he was in the flesh WHEN he was able to die.
Now Jesus is in the days of his flesh being incorruptible sitting at God’s right hand.
Acts 2: 30 Therefore being a prophet, and knowing that God had sworn with an oath to him, that of the fruit of his loins, ACCORDING TO THE FLESH, he would RAISE UP CHRIST to sit on his throne; 31 He seeing this before spake of the resurrection of Christ, that his soul was not left in hell, neither his flesh did see corruption.
There is quite a difference between the days Jesus was in the flesh able to die, verse the days when God gave eternal life to Jesus not allowing his flesh to see decay.
