Mark 11 & 12

So we read about Jesus riding in on a donkey.  So what is the significance of this? Zechariah 9:9 Tells us that the king of Zion will be riding on a donkey.  So this act of riding the donkey into town fulfilled the prophecy, and told everyone that he was the Messiah.
 
In the world we live in today we have thousands of rules and laws to tell us what we can and can't do chapter 12 lays it out real nice and simple for us all though.  Love the Lord our God with all your heart and soul, and love your neighbor as you do yourself.  If we could all figure out how to do this no other written law would be needed.
