It's dawned on me today that, as a man, Jesus also had human emotion. He experienced fear and apprehension, and gave us an example of how to overcome these flesh responses. As a human, it is not a sin for me to get angry, sad, confused. My duty is to take these emotions to God honestly and ask for guidance to handle them. Gospel of Matthew tells of Jesus's anger upon visiting a church that had become more of a trading post for business transactions than a place of worship. He referred to it as a "den of robbers" and overturned tables in his rage. This anger served the Lord's purpose, and was not sinful. Many prophecies were fulfilled on Matthew 2 and 3- in these, Joseph was warned in his dreams multiple times. He had fear and doubt about these visions, yet still followed God's will.
Edit: Psalm 2 confirms this as well.
