In my religion class this week, our professor drew our attention to the biblical rule of threes. Many, many, many times in the bible people, teachings, and phenomena will occur in sets of three. In Hebrew, saying something multiple times is an intensifier, like "holy holy is the Lord." But repeating something three times is the ultimate intensifier. "Wo, wo wo unto Jerusalem" is equivalent to saying Jerusalem is the woest. The most wo. This is like if Little Ceasar's "Extra Most Bestest" pizza was just called "pizza pizza pizza."
In Moses 1, after Satan tempts Moses to doubt himself and worship the devil, Moses tells Satan three times (in verses 16, 18, and 20 for those playing along at home) to depart. The "extra most bestest" of get-out-of-heres. But here's the twist: it doesn't work. Not until Moses commands the devil to leave in the name of the only begotten does Satan leave him alone.
What does this teach us? Invoking Christ's name and authority was more powerful than the extra-most-bestest command Moses could come up with on his own. This is one more bullet point on the long list of scriptural cases where man's best efforts prove to be futile until Christ's power is added into the mix. This same chapter also teaches us that we are great, mighty children of our Heavenly Father with infinite potential - but at the same time, we are nothing without our older brother, Jesus Christ.
