What are the passages to look at to see that Jesus never sinned?

Well let me see if I can call them to mind. In the Gospels his enemies were said to not be able to bring any charge against him. I don't remember the text.

In Hebrews 4, "We have a high priest who was tempted in every point like we are, yet without sin."

In Romans 8 you have Paul very carefully saying in verses 3 and 4 that he came in the likeness of sinful flesh.

There are two or three others and they're just not coming to my mind right now.

2 Corinthians 5:21

Yes, "he who knew no sin was counted as sin in order that we might become the righteousness of God." So he knew no sin.

Any others?

Jesus challenges the Pharisees to accuse him and they can't.

Yes, "who can charge me of any sin?" to the Pharisees. And they're not able to bring any charge against him.

There are one or two others, but I'll let it go at that. You have another one?

In him there was no deceit.

Yes, 1 Peter 2:22: "In him there was no deceit." "When he was reviled he did not revile in return," and "there was no deceit in his mouth."

So, excellent question. Jesus was without sin. He needed to be a spotless lamb, and he was a spotless lamb. The book of Hebrews would be a good place to go.
