John 13:33-35 NIV
“My children, I will be with you only a little longer. You will look for me, and just as I told the Jews, so I tell you now: Where I am going, you cannot come.
“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.”
“‘Love the Lord your God with all your heart and with all
your soul and with all your mind.’
This is the first and greatest commandment.
And the second is like it: ‘Love your neighbor as yourself.’”
Matthew 22:37-39 NIV
