Kainos is new but not just new its super-new. If yoi have an old pair of Nikes that get a Kainos upgrade they have not just been replaced but the new shoes now let you levitate, travel at light speed, supply enough power to light up the whole earth, and supply sustenance for all of mankind.
Andrew Farley, in his book The Naked Gospel, talks about how when Jesus came in and stepped into that roll of priesthood he did not follow the lineage that one would expect. The priesthood had to be transformed. A new beginning, a level (but kainos) playing field. Jesus came out a tribe that should not have been considered for priesthood. There had to be a breaking a transformation for the new. The Levitical system was based on the law. The law was a curse to man. Jesus came as kainos Adam, the final Adam.
18 That by two immutable things, in which it was impossible for God to lie, we might have a strong consolation, who have fled for refuge to lay hold on the hope set before us:
19 Which hope we have as an anchor of the soul, both sure and steadfast, and which enters into that within the veil;
20 Where the forerunner is for us entered, even Jesus, made an high priest for ever after the order of Melchizedek.
Hebrews 7:3 says that Melchizedek is without father or mothervor genealogy. Our origin was prior to Genesis 1. We were created not on our physical conception. We were defined in the mind of God before the earths creation. Mans origin is not reflected in Adam but in the mind of God.
Jesus came to earth and took that priestly Melchizedek mantle (kainos). He came as a man (incarnation). We were co-crucified, co-buried, co-resurrected, and co-ascended with him. We are complete in him. His death wiped out the Adamic/Levitical system of the law. That system was dependent on works. The devil wants you to believe that that system is still in effect.
It is all new, his act at calvary on the cross reconciled mankind to its pre Genesis identity. We are now closer to God then Adam. Adam walked with God, God is now found in man! Guys! This is better than Adam had it! KAINOS! This bring a whole new meaning to 2nd Corinthians 5:17:
Therefore, if anyone is in Christ, he is a new creation. The old has passed away; behold, the new has come.
My identity is found IN CHRIST. I can’t define God but he defines me, he is not an example for me but of me! Don’t be that guy who sees his face in the mirror and walks away and forgets what he saw.
What’s true of Him is true of you.
“The only difference between Christ and us was his understanding of who he was.”
