# if you favor

"give special treatment to" or "give honor to"

# committing sin

"sinning." That is, breaking the law.

# you are convicted by the law as transgressors

Here the law is spoken of as if it were a human judge. This can be translated using an active verb. Alternate translation: "the law itself convicts you of transgressing it" or "you are guilty of breaking God's law" (See: [[rc://en/ta/man/jit/figs-personification]])
