Why did Christ tell us to love our enemies?

Answer

"But 1 say unto you, Love your enemies, bless them that curse you, do good to them that hate you, and
pray for them which despitefully use you, and persecute you; that ye may be the children of your Father
which is in heaven: for He makes His sun to rise on the evil and on the good, and sends rain on the just and
on the unjust." Matt. 5: 44, 45.
