The consequences of hating enemies

"To keep you is no benefit. To destroy you is no loss."

quotes from Jesus:

"You have heard that it was said, 'You shall love your neighbor and hate your enemy.' But I say to you, Love your enemies and pray for those who persecute you, so that you may be children of your Father in heaven; for he makes his sun rise on the evil and on the good, and sends rain on the righteous and on the unrighteous.
For if you love those who love you, what reward do you have? Do not even the tax collectors do the same? And if you greet only your brothers and sisters, what more are you doing than others? Do not even the Gentiles do the same?
Be perfect, therefore, as your heavenly Father is perfect."
Matthew 5:43-48 NRSV

When the Pharisees heard that he had silenced the Sadducees, they gathered together, and one of them, a lawyer, asked him a question to test him. "Teacher, which commandment in the law is the greatest?"
He said to him, "'You shall love the Lord your God with all your heart, and with all your soul, and with all your mind.' This is the greatest and first commandment.
And a second is like it: 'You shall love your neighbor as yourself.'
On these two commandments hang all the law and the prophets."
Matthew 22:34-40 NRSV

"I give you a new commandment, that you love one another. Just as I have loved you, you also should love one another. By this everyone will know that you are my disciples, if you have love for one another."
John 13:34-35 NRSV

quote from St. Paul:

"Live in harmony with one another; do not be haughty, but associate with the lowly; do not claim to be wiser than you are. Do not repay anyone evil for evil, but take thought for what is noble in the sight of all. If it is possible, so far as it depends on you, live peaceably with all.
Beloved, never avenge yourselves, but leave room for the wrath of God; for it is written, ‘Vengeance is mine, I will repay, says the Lord.’ No, ‘if your enemies are hungry, feed them; if they are thirsty, give them something to drink; for by doing this you will heap burning coals on their heads.’
Do not be overcome by evil, but overcome evil with good."
Romans 12:16-21 NRSV
