There are plenty of verses in the Bible that we can take to mean that Jesus was perfect (“a lamb without blemish”, etc), but the Bible doesn’t say outright that Jesus was always perfect. On the contrary, Hebrews implies that Jesus was not always perfect, but rather became perfect at some point. Hebrews 5:7-9 (NIV) says:
During 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. Although he was a son, he learned obedience from what he suffered and, once made perfect, he became the source of eternal salvation for all who obey him
According to this passage, Jesus was not the source of salvation until after he was made perfect. This has important ramifications. It means that people who lived before Jesus was made perfect, did not have a source of salvation. Without a source of salvation during their lifetime, God’s most faithful servants, like Moses, King David, King Solomon, and the prophets, went to hell when they died. It also means that if Jesus was always God then God isn’t necessarily perfect. Alternatively, it means that Jesus wasn’t always God (because God is always perfect).
There is good evidence that the author of Hebrews didn’t believe that Jesus was God, at least not in a way that makes the Father and Jesus one and the same. Here is a good presentation of the evidence: www.prudentialpublishing.info/hebrews_view_of_Jesus.htm
Which do you think is true…
1) Jesus was always God but God can be imperfect
2) Jesus became God after he became perfect
3) Hebrews is not the Inerrant Word of God
