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 )
conclusion : 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.
1 John 3:4 " Whoever commits sin also commits lawlessness, and sin is lawlessness."
Ezekiel 18:20, "The soul who sins shall die. The son shall not bear the guilt of the father, nor the father bear the guilt of the son. The righteousness of the righteous shall be upon himself, and the wickedness of the wicked shall be upon himself.”
Matthew 18:3, “Assuredly, I say to you, unless you are converted and become as little children, you will by no means enter the kingdom of heaven."
Matthew 19:14, "But Jesus said, “Let the little children come to Me, and do not forbid them; for of such is the kingdom of heaven.”
If children are born sinners as TD and original sin teaches then Jesus teaches that to be His disciples we must be corrupt like the little children which is an oxymoron.
The teaching above by Jesus, Ezekiel and John confirms this is true and original sin is not. One becomes a sinner when they sin and become guilty of that sin not before. Babies are born innocent, not guilty. There is no DNA gene making one a sinner that is folklore.
hope this helps !!!
