“A new commandment I give unto you: that you love one another — as I have loved you, that you also love one another. By this shall all men know that you are my disciples — if you have love one to another.”
John 9:5

“Therefore, all things whatsoever you desire that men should do to you, do even so to them, for this is the law and the prophets.”
Matt 3:44

“And as you desire that men should do to you, do also to them likewise. For if you love only those who love you, what reward have you? For sinners also do even the same. And if you do good to them who only do good to you, what reward have you? For sinners also do even the same. And if you lend to them of whom you hope to receive, what reward have you? For sinners also lend to sinners, to receive as much again. But love your enemies, and do good, and lend hoping for nothing again, and your reward shall be great, and you shall be the children of the Highest. For he is kind unto the unthankful and the evil. Be therefore merciful as your Father also is merciful. Judge not and you shall not be judged. Condemn not and you shall not be condemned. Forgive and you shall be forgiven. Give and it shall be given unto you — good measure, pressed down and shaken together, and running over shall men give into your bosom. For with the same measure that you mete, it shall be measured to you again.”
Luke 5:11
