65. How does the tenth commandment differ from the other commandments in the second table?

It touches on the root of sin, namely the evil desires of the heart, from which all evil thoughts, words or deeds arise.

• Keep your heart with all diligence, for out of it spring the issues of life. (Proverbs 4:23)

So, the last commandment speaks of the root of all sin – selfishness. The opposite is love. Love is the fulfilment of the law.

• Love does no harm to a neighbour; therefore love is the fulfilment of the law. (Romans 13:10)
