If indeed you [really] fulfill the royal Law in accordance with the Scripture, You shall love your neighbor as [you love] yourself, you do well. [Lev. 19:18.]
But if you show servile regard (prejudice, favoritism) for people, you commit sin and are rebuked and convicted by the Law as violators and offenders.
For whosoever keeps the Law [as a] whole but stumbles and offends in one [single instance] has become guilty of [breaking] all of it.
For He Who said, You shall not commit adultery, also said, You shall not kill. If you do not commit adultery but do kill, you have become guilty of transgressing the [whole] Law. [Exod. 20:13, 14; Deut. 5:17, 18.]
So speak and so act as [people should] who are to be judged under the law of liberty [the moral instruction given by Christ, especially about love].
For to him who has shown no mercy the judgment [will be] merciless, but mercy [full of glad confidence] exults victoriously over judgment.
