Mistakes and Perfection

As I make my own efforts to do what is right and to grow as a person, I am keenly aware of all the mistakes I make. Sometimes I sin, but sometimes I just make mistakes. Particularly when doing something difficult, we are all prone to making mistakes from time to time. Was Christ the same? We know He never sinned, but I have to wonder if He ever did things that frustrated Him or that He felt embarrassed about. I wonder if He ever faced a difficult situation but afterward, though having done nothing unrighteous, said to Himself, “Aaargh, I could have done that better.”

Making mistakes is very humbling for me. Was it also for Jesus Christ, as He “continued from grace to grace” (Doctrine and Covenants 93:13)?

Before His death and resurrection, Christ commanded His followers to be perfect even as Heavenly Father is perfect. During a visit to the Nephites after His resurrection, He said the same thing but mentioned that He was also perfect. I think one part of perfection is having a perfect body; that’s one thing Christ had after His resurrection that He didn’t have before. I find it interesting that He modified the Sermon on the Mount slightly when giving it to the Nephites. (For example, adding the phrase “who come unto me” after the words “blessed are the poor in Spirit”—see 3 Nephi 12:3.)

Beyond that, I begin to wonder something else, challenging slightly a long-held idea. Perhaps this is a stupid question, and perhaps I should have read Talmage’s Jesus the Christ more so that I would have an easily referenced and definitive answer, but does being perfect mean being morally and righteously perfect only, or does it also mean never making mistakes? It seems strange to think of God making a mistake. If we are to become perfect, and thus reach a point at which we no longer make mistakes, how does that happen, and how long does it take?

Last thoughts for now:
Though I don’t expect to be certain about it any time soon, I imagine that Christ did make mistakes in His mortal life. Maybe it was just something like messing up a piece of wood when helping Joseph with the carpentry. It would certainly be understandable if He did. Either way, I expect to make many more of my own mistakes. If I didn’t, I’m sure I wouldn’t be living a life worth living.
