Jesus was born sinless and of a virgin
(Jesus said,) Can any of you prove me guilty of sin? If I am telling the truth, why don't you believe me? He who belongs to God hears what God says. The reason you do not hear is that you do not belong to God."
2 Corinthians 5:21
God made him (Jesus) who had no sin to be sin for us, so that in him we might become the righteousness of God.
For we do not have a high priest who is unable to sympathize with our weaknesses, but we have one who has been tempted in every way, just as we are-yet was without sin.
Such a high priest meets our need-one who is holy, blameless, pure, set apart from sinners, exalted above the heavens. Unlike the other high priests, he does not need to offer sacrifices day after day, first for his own sins, and then for the sins of the people. He sacrificed for their sins once for all when he offered himself.
1 John 3:5
But you know that he appeared so that he might take away our sins. And in him is no sin.
