The Golden Rule
"You have heard the saying, 'You shall love your neighbor and hate your
enemy.' But I say to you, love your enemies, bless those who curse you,
do good to those who hate you, and pray for those who persecute you,
that you may become sons of your Father in heaven; for he makes his sun
to rise on the wicked and the good alike, and sends rain on both those
who do right and those who do wrong. For if you love only those who love
you, what reward have you earned? Do not even the tax-gatherers as
much? And if you show courtesy only to your friends, what more are you
doing than others? Do not even the heathen do as much? You must
therefore become perfect, even as your heavenly Father is perfect.
"Therefore, whatever you wish that men should do to you, do even so to
them."
