Where is your statement above coming from? Jesus was a man upon earth for 33 years of his life and he broken the Golden Rule more than 15 times only within the text of Mat. 23:13-33. A sinful act is measured by the degree of an assault unto another and not by how you feel in your flesh.
A person can sin in word or deed, and even in thought. No one should ever hurt anyone else.
Romans 3:23 says all have sinned.
There are verses that say Jesus did not sin.
2 Corinthians 5:21 NASB - 21 He made Him who knew no sin to be sin on our behalf, so that we might become the righteousness of God in Him.
This second verse also talks about Jesus.
Hebrews 4:15 NASB - 15 For we do not have a high priest who cannot sympathize with our weaknesses, but One who has been tempted in all things as we are, yet without sin.
I don't have more than this at this time. There are other verses I believe.
