Hebrews 2:14.
John 1:14- And the Word became flesh (sarx) and dwelled among us and we beheld His glory, the glory of the only begotten from the Father full of grace and truth.
Hebrews 2- Since the children have flesh and blood, he too shared in their humanity so that by his death he might break the power of him who holds the power of death—that is, the devil—
15and free those who all their lives were held in slavery by their fear of death.
16For surely it is not angels he helps, but Abraham’s descendants.
17For this reason he had to be made like them,
k fully human in every way, in order that he might become a merciful and faithful high priest in service to God, and that he might make atonement for the sins of the people.
18Because he himself suffered when he was tempted, he is able to help those who are being tempted.
Above we see the Son through the Incarnation became sarx( flesh). Hebrews 2 says He shared that same flesh we have and was like us in every way.
So if Jesus came in the flesh ( John 1:1, 1 John 4:2, 2 John 1:7) then His humanity disproves the sin nature misnomer many teach and believe or one must admit Jesus was born with a fallen corrupt sinful nature and thus born a sinner like all men are born sinners according to the doctrine of Original Sin and TD. ( Total Depravity )
You see man in not born a sinner just like Jesus was not born a sinner. Jesus never sinned yet was born innocent like all men. We become sinners when we sin and become guilty of sin. This is why babies are innocent , not guilty until they sin.
hope this helps !!!
