Matthew 5:48
King James Version
“Be ye therefore perfect, even as your Father which is in heaven is perfect.”
Context
45That 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.
46For if ye love them which love you, what reward have ye? do not even the publicans the same?
47And if ye salute your brethren only, what do ye more do not even the publicans so?
48Be ye therefore perfect, even as your Father which is in heaven is perfect.
