Love Your Enemies

Matthew 5:43 Ye have heard that it hath been said, Thou shalt love
thy neighbour, and hate thine enemy.
44 But I 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;
45 That ye may be the children of your Father which is in heaven: for he
maketh his sun to rise on the evil and on the good, and sendeth rain
on the just and on the unjust.
46 For if ye love them which love you, what reward have ye?
do not even the publicans the same?
47 And if ye salute your brethren only, what do ye more than others?
do not even the publicans so?
48 Be ye therefore perfect, even as your Father which is in heaven
is perfect.
