When Christian theologians talk about the perfection of Christ, they are talking specifically about Jesus' sinlessness (both proper sins and sins of omission). However, did Jesus ever "mess up" in a non-sinful way? Absolutely.
He is fully man, and fully God.
But by adding a human nature to his divine nature, the second person of the Trinity willingly limited Himself on earth. (Think of it like taking the fastest man on earth, then putting him in a three-legged race with an obese ten-year-old with asthma. Is the man still the fastest man on earth . . . yes. But he can only go as fast as the ten-year-old.)
Ok, here's my point. Jesus in his humanity had to grow in wisdom and understanding:
And Jesus kept increasing in wisdom and stature, and in favor with God and men. - Luke 2:52
Furthermore, in his humanity, Jesus was limited in his knowledge:
"No one knows about that day or hour, not even the angels in heaven, nor the Son, but only the Father..." Matthew 24:36
This does not undercut Jesus' divinity, but emphasizes his humanity.
Jesus was both man and God simultaneously.
As such Jesus had to learn how to walk . . . even though his divine self would have already known how to do so. Jesus would have had to learn the Torah. I'm sure Jesus skinned his knee as a child.
Far too often Christians in evangelical circles focus solely on Jesus' divinity as a back-lash against trends that claim he was merely a man. We Christians, however, lose something very powerful in the incarnation when we do this . . . namely:
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. - Hebrews 4:15
