How complete is my picture of Jesus?

If Jesus didn't sin, how human was he?
 In this article, the author makes the assertion that sin is not an essential part of being human, so Jesus was completely human without sin. However, if sin was not a part of human nature, why is Jesus the only one who has not sinned? I think that although Jesus was fully human, and was undoubtedly tempted to sin many times, he was also the son of God. It may not be a part of human nature to sin, but the will of humans   is to weak to resist every temptation to sin that we face.

Does that mean that Jesus never had to be forgiven?
Although Jesus never committed a "sin" in the technical sense of the word, he probably regretted some of his less wise decisions or actions. Jesus never deliberately defied God's will, but he must have made some mistakes during his life. Even though they were not sins, Jesus repented his actions and was forgiven for them.

Is it a problem to say that perhaps Jesus did sin?
As I have said in my previous answers, because Jesus was the son of God, he never deliberately went against his father's will. Although Jesus never purposely sinned, I think he did mess up every now and then. However, because Jesus' mistakes were unintentional, they were not actually a sin. Jesus was only human, and he made his share of mistakes like the rest of us, but he was also divine, and was able to resist the temptation to sin.
