Do not worship any other god than the one true God.
Do not merely listen to the word, and so deceive yourself. Do what it says.
A new command I give you: Love one another. As I have loved you, so you must love one another. By this everyone will know that you are my disciples, if you love one another.
Then Jesus said to those Jews who believed him, "If you abide in my word, you are my disciples."
