"Observe your enemies, for they first find out your faults." - Antisthenes
“Love is the only force capable of transforming an enemy into friend.” - Martin Luther King, Jr.
“He who seeks vengeance must dig two graves: one for his enemy and one for himself” - Chinese Proverbs
“The best way to destroy an enemy is to make him a friend.” - Abraham Lincoln
This wisdom is recorded in the bible in Matthew 5:43-48 (NKJV):
"You have heard that it was said, '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 spitefully use you and persecute you, that you may be sons of your Father in heaven; for He makes His sun rise on the evil and on the good, and sends rain on the just and on the unjust. For if you love those who love you, what reward have you? Do not even the tax collectors do the same? And if you greet your brethren only, what do you do more than others? Do not even the tax collectors do so? Therefore you shall be perfect, just as your Father in heaven is perfect.
