Direct quotes of Jesus about the law?

Jesus commanded that we follow two commands, that cover the old law completely. 

1. Love the Lord your God with all your heart, your soul and your mind. 

2. Love your neighbor as you love yourself. 

When we make the choice to believe in Him, deciding that what He did is truth, that means we believe and we follow what He said and continues to say through the Bible, God's Holy Word. 

This doesn't mean we don't question it and weigh it, this means we hold onto it as our core beliefs. This means when we do question it, we can find the answers in it as well!
