Deuteronomy 31

Moses had an apparently pointless job.  He was to teach the Israelites God's laws and encourage them to obey, all the while knowing that they wouldn't.  How discouraging!  But Moses wasn't discouraged.  He faithfully obeyed and did his best.  Although the Israelites failed, future generations (even we) benefited, because now we have God's laws written down for us.  When my job seems hopeless, I'll try to remember that.
